Capacitor three-point sine wave oscillation circuit

Filter 18.432M


Experimental content:
1. Observe the start-up process and observe the start-up process with an oscilloscope.
2. Measure the oscillation frequency f0
f 0 = 1 2 π LC 1 C 2 C 1 + C 2
Measure the period of the output waveform T≈44.64μs, calculate the frequency f 0 = 1 T
Measured value: f0≈22.42kHz
Calculated value: f0=22.52kHz
