High-Pass and Low-Pass Filters


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:

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

Lecturer Procedure
Step(s) to Follow Expected Result

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

Attentuation will occur at the critical frequency, noted on the individual filters.
