| Abstract: | Technology of phase-locked loop is widely used on frequency modulation and demodula tion in the area of modern communications. A phase-locked loop contains mainly a phase detector, a low pass filter of loop, and a voltage-controlled oscillator. This thesis, making use of Simulink in MAT LAB, constructs visually digital phase-locked loop simulation models of frequency modulator and demod ulator and verifies the characteristic of following signals in digital phase-locked loop systems. |
| Keywords: | simulink digital signal phase-locked loop FM |
