ABSTRACT:
A receiver for frequency modulated channels comprises two phase quadrature channels with synchronous demodulation and low-pass filtering. The object aimed at is to provide a tunable receiver without input filter. The absence of an input filter excludes the use of a limiter and the receiver will then be sensitive to amplitude variations. This problem has been solved by dividing the signals in the receiver in one or two stages by an amplitude factor which is derived from the output signals of the low-phase filters.
