Title: Improvements in receivers for frequency modulated waves
IPC: H04L27/14
Filed: 1945-10-09
Abstract: 606,275. Frequency mediation. DEHN, F. B. (Press Wireless, Inc.). Oct. 9, 1945, No. 26320. [Class 40 (v)] In a signalling system of the type in which a carrier is varied in frequency between two limits, the receiver is provided with means for maintaining the potential of a point which corresponds to the detected signals independent of undesired frequency shifts, due, for example, to frequency wander at the transmitter or receiver. Signals arriving at the receiver 9 are heterodyned by oscillator 10 and fed to discriminator 11, the output being passed through a low-pass filter 12 to remove undesired noise components. Since the waveform from filter 12 is more sinusoidal it is distorted to rectangular form in limiter 13, the D.C. component first being removed as this causes variations in the width of the waveform from the limiter, Rectifiers 18, 20 are arranged to conduct during alternate half-cycles, the resulting current flowing through load resistors 19, 22 so that a centre tap on resistors 24, 25 gives an output free from a D.C. component. The output from the limiter may operate a facsimile reproducer 14 or telegraph keyer 26 and the input may be employed to operate a recorder 30. When a transmission involves shading, impulses representing black and white are transmitted to set the correct level.
