High speed front end of the multimegabit telemetry demodulator detector
Abstract
The high speed front end (HSFE) portion of the Multimegabit Telemetry Demodulator-Detector is discussed. The HSFE accepts in-phase and quadrature analog signals from the input signal conditioner. It samples them with analog-to-digital converters at maximum rate of 64 megasamples per second. The samples are processed digitally and the integrals of I, Q, and of their crossproduct over one symbol period are supplied at symbol rate to the rest of the system.
