Analog-to-digital signal processing in a prototype SATCOM signal analyzer

A prototype SATCOM Signal Analyzer (SSA) has been designed which performs spectral analysis on transponder signals from the Navy's UHF communications satellites. As an integral part of the SSA, the Analog to Digital Control and Conversion subsystem converts four channels of baseband analog signals into equivalent digital representations while operating at variable sampling rates and offering either twelve or eight bits of resolution of the analog signal. The digital data thus derived is presented to an array processor for Fast Fourier Transform processing. This report documents the design and construction of the Analog to Digital Control and Conversion subsystem.(Author)
