Suppose you are given the circuit of Figure 49.1 supplied with two 1-kHz signals of exactly the same amplitude, but exactly 180 degrees out of phase (Vini with a signal at 0 degrees and Vin2 with a signal of 180 de- grees). Discuss what you would expect to see at the output of the sum- ming amplifier, Include a description of the amplifier operation that would produce the output you expect. 2. Given the circuit of Figure 49.1, what sort of output signal would you expect to see if one input were a l-kHz signal and the other was a 2-kHz signal?

1) Oscillator is widely used in the radio frequency circuits. It performs a simplicity application and better phase noise attributes. It is constructed by using passive elements such as resistors, inductors and capacitors. The oscillator basically contains two systems; square wave generator and filter as shown in Figure 1. Square wave generator is applied as an input signal to the oscillator. On the other hand, filter is applied to remove the certain frequencies from square wave in order to produce an output signal of simusoidal frequency. One periodic square-wave signal is shown in Figure 2. Evaluate the Fourier coefficients for the signal. What is the expectation of the frequency spectrum of the simusoidal output signal?
