Universal Demodulator with Phase-locked Loops
Original language description
Universal demodulator with phase-locked loops has been designed and developed in the Laboratory of Transmitters and Receivers at the Department of Radio Engineering. The universal demodulator with phase-locked loop demodulates angle modulated signal in wide frequency range (hundreds kHz according to the setting). Further phase-locked loop is used for carrier regeneration which makes possible coherent demodulation of amplitude modulated signal. It is possible to adjust lock and capture range so that behavior of phase-locked loop is tested for various values of ranges according to application requirements (as example demodulations of wide-band or narrow-band frequency modulated signals). This universal demodulator with phase-locked loops was used for measurement of characteristics and parameters of demodulators and phase-locked loops and comparison with theory.
