Frequency response of filter circuit¶
Transmission of electrical signals though a filter circuit depends on the frequency. The ratio of the output voltage to the input is called gain. Plotting gain as a function of frequency gives the frequency response curve of a filter circuit.
Objective
Draw the frequncy response curve of a fileter circuit, with
. Expected resonant frequency of the bandpass filter
Procedure
- Assemble the LCR filter circuit on a bread board
- Connect WG and A1 to the filter circuit input
- A2 to the output
