INTRODUCTION The purpose of this experiment is to introduce the PCM ENCODER module. This module generates a pulse code modulated - PCM - output signal from an analog input message. In this experiment the module will be used in isolation; that is, it will not be part of a larger system. The formatting of a PCM signal will be examined in the time domain. L-24 In this picture the circuit setup generates PCM code for the analog values. L-25 In this picture DMM is used to record the analog…

Objectives: Generate a FM signal by using a VCO (voltage controlled oscillator). Use two VCO to create a PPL (phase locked-loop) to lock the signal produced by the VCO to keep it from drifting away from the set frequency. Results: As the gain is increased on the VCO the waveform for the FM signal is less in the trough than when the gain is lower. When the frequency drift from the incoming signal we can use a PLL so the output signal matches the input signal. Conclusions: Using the VCO we…
