LC Resonance circuits

# The LC cicuit

- Design a
**parallel**LC resonant circuit with a resonant frequency between 50-200 kHz. use = 10 - 100 , R = 1k . - Construct the LC circuit using a non-polar capacitor
- Measure the Gain as a function of frequency. (25 pnts)
- Compare the measured and theoretical values of the resonance frequency ( ) (10 pnts)

## Questions

- What is the bandwidth of the above circuit? (5 pnts)

# The RLC cicuit

- Design and construct a
**series**LRC circuit. - Measure and Graph the Gain as a function of the oscillating input voltage frequency. (25 pnts)
- Measure and Graph the Phase Shift as a function of the oscillating input voltage frequency. (25 pnts)

## Questions
