Explanation: Free running multivibrator operates at a frequency which is determined by an external tuning capacitor and a resistor. On applying a dc control voltage the frequency can be shifted on either sides. This frequency deviation is directly proportional to the dc control voltage and hence it is called as ‘voltage controlled oscillator’. 2. The output voltage of phase detector is
