Test 1 tips

Physics 230, Spring 2007

These are the kinds of questions you should expect on test 1.

1. Quick identification

You should be able to recognize the following kinds of circuits and explain their purpose in two or three sentences:

• High pass filters of various designs
• Low pass filters of various designs
• Band pass filters of various designs
• Band reject and notch filters of various designs
• Clipper circuits
• Zener regulators
• Common emitter amplifiers
• Emitter follower amplifiers
• Common base amplifiers
• Voltage regulators, both pass and shunt.
• Crowbar circuits.

2. Filters and complex circuits

Given a filter circuit involving resistors, capacitors, and/or inductors, determine |V_in/V_out| and phase shift of V_out with respect to V_in as a function of frequency. Be able to determine the amplitude and phase shift of V_out at on particular frequency, given the amplitude of V_in.

3.Circuit design

Be able to design a multistage amplifier circuit using conservative design principles for any specified gain, source impedance, and load resistance, that works over a specified frequency range.

You will be able to use CircuitMaker, but you are on your honor not to call up previously designed circuits.
