Lab-Volt / LabVolt 9445-00 PCM Decoder for Digital Communications Training Systems - Training / Education

Description

<p>The PCM Decoder is used to demodulate a serial PCM signal generated by the PCM Encoder, or a parallel PCM signal generated by either the PCM Encoder or the DPCM Decoder, and to recover the original analog signal. A bar graph indicator for the test bus shows the logic states of the 8-bit D/A converter input. Using the PCM Decoder, students gain familiarity with PCM decoding and D/A conversion processes. The effects of compression and expansion on weak and strong signals can be investigated also.
