Quadrature demodulator (10) and quadrature modulator (30) which comprise a first oscillator (11) and a second oscillator (12), a separate excitation signal being fed to the first osciallator (11) and second oscillator (12) in order to determine the point in time at which switching between two stable states takes place, and the quadrature demodulator (10) and quadrature modulator (30) further comprise excitation means (17, 18).Electrical Engineering, Mathematics and Computer Scienc
