Consider the digital filter with an impulse response for which the Z- transform is: (z 1)2 H(z) = (z-0.7-jo.7)(z-0.7 j0.7) a- Draw the location of zeros and poles of this function in relation to the complex unit circle. b- If this filter is operated at a sampling frequency of 48 kHz, which (approximate) input frequency will experience the lowest attenuation? c- Draw a direct form I block diagram representation of this digital filter
