EE 200: Homework Assignment #8

Date Assigned: Friday, March 7, 1997
Date Due: Wednesday, March 12 and Friday, March 14, 1997

Reading: Relevant reading in the text to supplement the class notes are sections 6.1, 6.2, 6.3, 7.1, and 7.2.

Problems: Please submit solutions to the following problems on Wednesday, March 12.

  1. For each sine wave, find the phasor representation (in polar form), and sketch the phasor in the complex plane.
    1. tex2html_wrap_inline61
    2. tex2html_wrap_inline63
  2. For each phasor, express the corresponding sine wave as a time function, and sketch the sine wave versus time. Assume tex2html_wrap_inline65.
    1. tex2html_wrap_inline67
    2. tex2html_wrap_inline69
  3. Find the magnitude of each complex number below.
    1. tex2html_wrap_inline71
    2. tex2html_wrap_inline73
    3. tex2html_wrap_inline75
    4. tex2html_wrap_inline77

Please submit solutions to the following problems on Friday, March 14.

  1. A circuit and its phasor/impedance equivalent are shown below. Determine the current i(t), and sketch i(t) versus t. Indicate the sine wave amplitude, frequency, and phase in the sketch. Note that tex2html_wrap_inline85.

  2. Classify each circuit below as one of the following types of filter: low-pass, high-pass, or band-pass. You can do this either by thinking about how each circuit operates as tex2html_wrap_inline87 and tex2html_wrap_inline89, or you can analyze the circuits as voltage dividers with impedances and study the resulting equations.
