  • Premodulation filter for generating a generalized tamed frequency modulated signal
    Patent number: 4531221
    Abstract: A transmitter for transmitting a carrier whose frequency is modulated by pseudo five-level signals. In order to obtain a simple receiver and an improved signal-to-noise ratio, a substantially three-level signal is generated in the transmitter at the detection instants t=(2m-1)T/2 by means of a pre-modulation filter.
