1. a) Sketch the block diagrams of the natural and flat-top sampling (PAM) circuits. What is the main difference between these two methods? b) A linear delta modulator is designed to operate on speech signals limited to 3.4 kHz. The specifications of the modulator are as follows: Sampling rate = 10fNyquist, where fNyquist is the Nyquist rate of the speech signal. ▸ Step size A = 100 mV. The modulator is tested with a 1 kHz sinusoidal signal. Determine the maximum amplitude of this test signal required to avoid slope overload.
