1. Determine the frequency of oscillation of a three-stage Phase shift ladder network oscillator in which c = 110 nF and R = 130 kN (10 points) 2. If C = C2 = 70 nF, determine the output frequencies produced by this arrangement (a) when R = R2 = 1.2kn and (b) when Ri R2 = 4k1. (20 points) 3. A Colpitts Oscillator circuit having two (2) capacitors of 37 nF and 350 nF respectively are connected in parallel with an inductor of 30 mH. Determine the frequency of oscillations of the circuit, the feedback fraction and draw the circuit. (20 points)
