1. a. Write a matlab code to design a chirp signal x(n) which has frequency, 700 Hz at 0 seconds and reaches 1.5kHz by end of 10th second. Assume sampling frequency of 8kHz b. Design an IIR filterto have a notch at 1kHz using fdatool. ELEC 30001 (QP) Page 1 of 2 Digital Signal Processing ELEC 30001 - Fall-17-cW1-All-QP C. Plot the spectrum of signal before and after filtering on a scale- to . Observe the plot and comment on the range of peaks from the plot. d. Critically analyzethe design specification. e. Demonstrate the working of filter by producing sound before and after filtering using necessary functions
