QUESTION 3 Figure 2 depicts the schematic diagram of a phase shift oscillator . Figure 2 Phase shift oscillator for Question 3 The circuit will oscillate if it is designed to have poles on the jv-axis. 3.1Show that the transfer function for the passive network in the circuit is given by π2(π ) π1(π ) = β1 (1 + 1 π π πΆ) (2 + 1 π π πΆ) 2 β 3 β 2 π π πΆ (10) 3.2Show that the oscillatorβs characteristic equation is given by 1 β πΎ 1 (1 + 1 π π πΆ) (2 + 1 π π πΆ) 2 β 3 β 2 π π πΆ = 0 (10) [20]
