A PCM Experiment for the Senior Electronic Laboratory

An experiment on pulse-code modulation designed for the senior-year electronics student is described. PCM is pedagogically desirable for its embodiment of a wide variety of pulse and digital techniques. The experiment draws upon the component-type experiences typical of undergraduate courses and integrates them into a complex system study. Emphasis is on functional interaction rather than on how a particular circuit accomplishes its function. Sixteen level quantization is used with provision for injection of noise and variation of system parameters.
