## Get ahead in your ENG203 Filter Theory and Design course by studying samples of exemplary assignments!

Singaporeassignmenthelp.com provides you with an array of resources and samples to help you understand the material covered in ENG203 Filter Theory and Design course. These include assignments from various universities, including NUS, NTU and SMU. Students can use these resources to get familiar with the topics covered in this course, as well as to develop their skills in designing filter circuits for different applications.

Here, we will provide some assignment tasks. These are:

### Assignment Task 1: Sketch the frequency response of the filter, zeros & poles of the filter in the s-plane and z-plane and block diagram representation of filters.

In signal processing, filters play a crucial role in shaping and modifying signals to extract meaningful information. Understanding the frequency response of filters, and the placement of zeros and poles in the s-plane and z-plane, is essential to designing effective filters. The frequency response of a filter describes how it affects the amplitude and phase of a sinusoidal input signal as a function of frequency.

By analyzing the zeros and poles of a filter in the s-plane and z-plane, we can gain insight into the filter’s stability, causality, and frequency response. Moreover, a block diagram representation of a filter provides a visual depiction of its components and their interconnections. By studying the frequency response, zeros and poles, and block diagram of filters, we are better equipped to design and implement filters that meet a variety of signal processing needs.

### Assignment Task 2: Give the transfer function of the filter.

In order to fully understand the capabilities of a filter, it is important to have a clear understanding of its transfer function. The transfer function essentially describes the input-output behavior of a system and can be used to analyze and optimize its performance. By examining the transfer function of a filter, one can assess its ability to attenuate unwanted frequencies and pass desired ones.

This information is crucial in many applications, such as digital signal processing and telecommunications. With a comprehensive understanding of a filter’s transfer function, engineers and technicians can make informed decisions about which filter is best suited for their specific application, ultimately leading to improved performance and overall efficiency.

### Assignment Task 3: Discuss Butterworth, Chebyshev type I, II filter designs.

When it comes to filtering designs, there are several effective options to consider. Two of the most popular are the Butterworth and Chebyshev type I and II filters. Butterworth filters are known for their smooth frequency response and lack of ripples in the passband, making them ideal for applications that require a flat response. On the other hand, Chebyshev filters allow for steeper roll-off rates and have ripple in the passband, making them useful in situations where a sharper cutoff is needed.

Chebyshev type I filters has ripple only in the passband, while Chebyshev type II filters have ripple only in the stopband. Ultimately, the choice between these filter designs will depend on the specific needs of your project and the type of signal you are working with.

### Assignment Task 4: Use the frequency transformation method and bilinear transformation method to design filters.

The process of designing filters can be a challenging task, but with the help of the frequency transformation method and bilinear transformation method, it can be made more seamless. The frequency transformation method is used to convert an analog filter into a digital one, while the bilinear transformation method is often employed to design IIR filters.

Both methods have their advantages and disadvantages, and it is essential to determine which one is best suited for a particular application. By using these methods, engineers and researchers can design filters that effectively remove unwanted noise and interference from signals, resulting in a more accurate and reliable data analysis.

### Assignment Task 5: Analyze filter response and filter parameters.

When it comes to analyzing filter response and filter parameters, it’s important to have a deep understanding of the underlying technical concepts. From low-pass and high-pass filters to band-pass and notch filters, there are a variety of filtering techniques that engineers can use to manipulate signals and reduce noise.

But it’s not just about selecting the right filter type – it’s also important to adjust the filter parameters (such as cutoff frequency or Q factor) to optimize the filter response. By carefully analyzing filter response curves and making adjustments based on specific applications, engineers can improve system performance and ensure that their designs meet the necessary specifications.

### Assignment Task 6: Compute cutoff frequencies, gain, roll-off, order, output signal and other parameters of filters.

When it comes to designing and implementing filters, understanding various parameters is key to achieving desired outcomes. Cut-off frequencies, gain, roll-off, order, and output signal are some of the essential parameters to consider. Cut-off frequencies determine the range of frequencies that will pass and those that will be blocked, while gain refers to the amplification of the signal.

Roll-off is the rate of signal attenuation beyond the cut-off frequency, while order refers to the number of poles or zeros in the transfer function. The output signal, on the other hand, is the filtered version of the input signal. Understanding these parameters is important to achieve the desired frequency response from your filter design.

### Assignment Task 7: Determine the various responses (impulse, natural, forced) of the given system.

When analyzing a system, it is important to consider the different types of responses that can occur. These responses can be classified as impulse, natural or forced, depending on the input applied to the system. An impulse response is characterized by a sudden, brief input and is useful for determining the system’s ability to respond quickly to changes. The natural response refers to the system’s natural oscillations that occur after a disturbance, without any external input.

Finally, the forced response is the system’s response to an input that is not part of its natural behavior. By analyzing these different types of responses, we can gain a better understanding of how the system behaves under different conditions and make informed decisions in designing or controlling it.

### Assignment Task 8: Design FIR and IIR filters using the specified method.

When it comes to designing FIR and IIR filters, it is important to have a solid understanding of the methods used to create them. By utilizing the specified methods for each type of filter, professionals in the field can create effective solutions that meet the needs of their clients.

Accurate design is crucial when it comes to filtering, as the wrong strategy could result in unwanted effects on the signal being filtered. With the right knowledge and tools, designing FIR and IIR filters can be a smooth and efficient process, providing the desired outcome for those in need of advanced filtration solutions.
