Can someone help me with this question please.
The resolution of a filter bank is determined by frequency response of the LPF used in the channels. A continuos-time signal is sampled at 10kHz and a 250 Hz frequency resolution is desired.
(a) If a Hanning filter is employed as the channel LPF, what the minimum filter length is needed?
(b) Design a Hanning filter that will satisfy this resolution requirment. Plot the filter magnitude response for at least two channels, one is centeredat freq=0, another is centered at the 250 Hz. Use Linear scale in Y-axis, X -axis is in Hz
(c) If a Blackman filter is employed as the channel LPF, what the minimum filter length is needed?
(d) Design a Blackman filter that will satisfy this resolution requirement. Plot the filter magnitude for at least two channels, Plot the filter magnitude response for at least two channels, one is centeredat freq=0, another is centered at the 250 Hz. Use Linear scale in Y-axis, X -axis is in Hz
