6.[10pt] The sinusoidal wave m(t) = 6sin(2πt) is transmitted using a 4-bit binary PCM system. The quantizer is of the midrise type, with a step size of 1. Sketch the resulting PCM wave for one complete cycle of the input. Assume a sampling rate of four samples per second, with samples taken at t = 0, 0.25, 0.5, and 0.75 seconds.
