A quantizer accepts a continuous-time input signal and responds with a continuous-time output signal that only has a finite number of equally spaced values. If xin(t) is the input signal and xout(t) is the output signal and q is the difference between adjacent output levels, the value of x out (t) at any point in time can be computed by forming the ratio xin(t)/q, rounding it off to the nearest integer and then multiplying the result by q. Let the range of the signal levels accepted by the quantizer be from ?10 to +10 and let the number of quantization levels be 16. Find the numerical total harmonic distortion (see Example 6.4 in Chapter 6) of the quantizer output signal if the input signal is xin(t) = 10 sin (2000?t).
