Transmitter for angle-modulated signals having an input for binary signals, a premodulation filter and a frequency modulation arrangement. In order to improve the error rate of the system of transmitter and receiver a premodulation filter is used having a pulse response h(t): <IMAGE> wherein g(t) is the pulse response of a Gaussian low-pass filter and T the duration of a binary signal element. The postdemodulation filter 6-4 (6-5) has a pulse response of the same general form for optimum results.
