Problem 4: Design a first-order, strictly causal, low-pass DT filter to recover a low frequency sensor signal, corrupted by high frequency noise. The signal can contain frequencies up to 10HZ and the noise has frequencies above IkHz. The sampling frequency is 20kHz and you may assume that there is no aliasing. If the highest distortion allowed for the signal is 1% in amplitude, what is the worst-case attenuation of the noise signal? Problem 4: Design a first-order, strictly causal, low-pass...
