PCM Telemetry Encoder

PCM Telemetry Encoder [Pulse Code Modulation] is used to encode the data in a serial digital format, and transmit it on a carrier to another location for decoding and analysis. PCM systems are less susceptible to noise than analog systems, and the digital data is easier to transmit, record, and an
