A lincar delta modulator is designed to operate on speech signals limited to 3.4 kHz. The specifications of the modulator are as follows: > Sampling rate = 10fxyqsiat; where fxyquise is the Nyquist rate of the speech signal. > Step size A = 100 mV. %3D The modulator is tested with a 1-kHz sinusoidal signal. Determine the maximum ampli- tude of this test signal required to avoid slope overload.
