Draw Gain frequency plots of four varieties of Ideal filters. Clearly label the Gain and frequency axes. Discuss why the plot is only up to /2.

1 Discuss why Linear phase is important in a Filter. 2 Design a FIR filter using the Kaizer window method for the sepcifications: Edge of pass band = 0.21 Edge of stop band = 0.311 Pass band ripple = 0.25 dB Minimum stopband attenuation = 50 dB 3 Draw a diagram of a Digital filter indicating its inputs and outputs in the time-domain and the frequency-domain. 4 Draw Gain frequency plots of four varieties of Ideal filters. Clearly label the Gain and frequency axes. Discuss why the plot is only up to F,/2 5 Draw a clearly labelled diagram indicating parameters/specifications of an actual filter 6 Indicate the components that are required to realize a digital filter 7 Compare and contrast the Rectangular, Hamming and Blackman windows used for design of FIR filters. 8 Indicate the three parameters which can be used to describe a discrete system. Discuss how to derive one parameter from any of the other two 1 Discuss why Linear phase is important in a Filter. 2 Design a FIR filter using the Kaizer window method for the sepcifications: Edge of pass band = 0.21 Edge of stop band = 0.311 Pass band ripple = 0.25 dB Minimum stopband attenuation = 50 dB 3 Draw a diagram of a Digital filter indicating its inputs and outputs in the time-domain and the frequency-domain. 4 Draw Gain frequency plots of four varieties of Ideal filters.
