High-Pass and Low-Pass Filters

Identifier: E&M: AC - 011

A function generator sends a signal to both inputs of the oscilloscope - 1 input is connected to a filter, the other is not.

Concept Overview:

Attenuation caused by the presence of a low-pass and/or high-pass filter on an AC signal.

Lecture Procedure

Step(s) to Follow

  1. Turn on function generator and oscilloscope, if not already done.
  2. Adjust the frequency of the function generator and make note of the results

Expected Result

Attenuation will occur at the critical frequency, noted on the individual filters
