ABSTRACT:
A band-compressor devices designed to match to one another two systems having different pass bands, comprises means for coding input signals in the form of N digital signals corresponding, at any instant, to the amplitude of the input signal with respect to N quantizing levels. N bistable trigger stages of RS or JK type, followed by as many D-type bistable stages, are provided to receive said digital signals on the one hand and pulses furnished by a clock on the other. The output signals from the bistable stages of type D are then recombined in an adder in order to furnish analog signals or in a coder for furnishing signals in binary form.
