The invention relates to a receiver for the reception of information pulse signals transmitted by means of n-phase modulation wherein the original information pulses coincide with different pulses from a series of equidistant clock pulses, the receiver including an n-phase demodulator which is provided with a plurality of parallel arranged synchronous demodulators which are fed by carriers having mutually different reference phases originating from a local carrier generator which is stabilised in phase on the carrier associated with the received signals, signal channels being connected to the outputs of the n-phase demodulator including sampling circuits controlled by a local clock pulse generator the output signal of which sampling circuits characterizes the phase of the received carrier relative to the relevant reference phase of the local carrier at the instants of the local clock pulses, the receiver furthermore being provided with combination circuits connected to the sampling circuits, which combination circuits characterize each of the n-possible phase sectors of the transmitted signals in a phase diagram by means of a separate combination of the outputs of the signal channels.
