Description

The Digital Communications 1 module enables students to configure, operate, and troubleshoot the following circuits:

• Pulse-Amplitude Modulation

• PAM Time-Domain Multiplexing

• Pulse-Time Modulation (PWM and PPM)

• Pulse-Code Modulation and Time-Division Multiplexing of PCM Signals

• Delta Modulation

• Channel Effects

Each circuit block contains a modulator for transmission and a demodulator for reception. Students learn the operation and function of the following:

• Sampler

• Sample/Hold

• Adder

• Ramp Generator

• Comparator

• Limiter

• Filter

• CODEC

• PLL

• Compressor

• Expander

• Integrator

• Differentiator

• Latched Compare

• Speaker Amplifier

• Channel Simulator

Features & Benefits

• Each circuit block contains a modulator for transmission and a demodulator for reception.
