1. Perform all steps given in previous lab#07 manual to generate the Frequency modulated signal.2. First PLL IC CD4046 is used for FM modulation and second CD4046 is used for demodulation of FM modulated signal. 3. Build the circuit shown in Figure 1 for FM modulation and demodulation. It is not necessary to use the buffer and output low pass filter.4. Show the spectrum of your FM demodulated signal to the instructor
