EE 230 Assignment 2 Spring 2009 Problem 1 Plot two periods of square wave that is symmetric with respect to the horizontal axis with peak value of 1 volt and a period of 1 sec. On the same axis, plot a) the fundamental b) the first 7 harmonics c) the sum of the fundamental and the first 7 harmonics Problem 2 What is the THD of the Sherwood RX 4503 receiver? Over what frequency range is the amplifier in this receiver specified to operate? How much gain deviation could occur over this frequency range? Problem 3 Consider the circuit shown below. a) Determine the phasor-domain transfer function relating V OUT and V IN b) Obtain the corresponding s-domain transfer function c) Determine the steady-state output if V IN =0.5sin1000t Problem 4 A power amplifier has an output impedance of 8 Ώ and an open-circuit RMS voltage of 64V a) Determine the power this amplifier will deliver to a 4 Ώ load, to an 8 Ώ load, and to a 1K Ώ load b) What would be the open-circuit voltage of the amplifier if the signal level

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
