Abstract
Quadrature demodulator and quadrature modulator which comprise a first oscillator and a second oscillator, a separate excitation signal being fed to the first and second oscillator to determine the time at which switching between two stable states takes place, and the quadrature demodulator and quadrature modulator further comprise excitation elements In the quadrature demodulator, an input signal is fed, which influences a parameter of one of the elements of the first and the second oscillator and produces a set of quadrature output signals. In the quadrature modulator, a first and second quadrature signals are fed to the quadrature modulator, which influences a parameter of one of the elements of the first and the second oscillator, and the quadrature modulator further comprises summing elements to produce a modulated output signal.
