Description : On the Direct CONVERSION RECEIVER View

Introduction
Very much like its well-established superheterodyne RECEIVER counterpart, introduced in 1918 by Armstrong [1], the origins of the DCR date back to the first half of last century when a SINGLE down-CONVERSION RECEIVER was first described by F.M. Colebrook in 1924 [2], and the term homodynewas applied. Additional developments led to the publication in 1947 of an article by D. G. Tucker [3], which first coined the term synchrodyne, in a RECEIVER, which was designed as a precision demodulator for measurement equipment rather than a radio. Another paper by the latter in 1954 [4] reports the various SINGLE down-CONVERSION RECEIVERs published at the time, and clarifies the difference between the homodyne (sometimes referred to as coherent detector) and the synchrodyne RECEIVERs: the former obtains the Local Oscillator (LO) directly, for example, from the transmitter, whereas the latter synchronizes a free-running LO to the incoming carrier.
