4. Determine the impulse response h[n] of a DT system with a frequency response as shown. The DT system is used with an ADC and DAC that operate with 8KHZ sampling frequency. Express h[n] in terms of the unit impulse and sinc functions. Magnitude Response A1 A2 -f, Hz f1 f2 Parameters: A1=4, A2=2, fl=2.25KHZ, f2=3KHZ 4.
