# 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 frequency response curve of a filter circuit, with L= 10μ H,C= 1μ F R= 100. Expected resonant frequency of the bandpass filter f0=(1)/((2π√(LC))

# Procedure

- Assemble the LCR filter circuit on a bread board
- Connect WG and A1 to the filter circuit input
- A2 to the output
