An FM demodulator using a PLL has a center frequency of 2 kHz and is implemented as a first-order loop. The input signal alternates between 1.95 kHz and2.05 kHz at a rate of 200 Hz with instantaneous transitions between the two frequency values. Sketch the demodulated output voltage waveform, ignoring the term related to the sum of the frequencies at the PLL input and the VCO output. For the PLL, use A=1,K_D=2.55 V/rad and K_O=0.93ω_osc, where ω_osc is the free-running frequency in rad/sec.
