Components
Use R1 = R3 from the integrator.
Make Rfosc = R1 = R3 and use Cf from the integrator.
Tosc ≈ 2.2RfoscCf (12.26)
Note that Tosc is about ½ of the design Tmax from the integrator or about 50 ms.

Procedure
- Turn off the power supply to reconnect the circuit into the oscillator configuration. Note the connection of Chan1_in, which measures the capacitor voltage.
- The main VI, Oscillator.vi(below), contains subVI’s CountCycles.vi and T.vi.CountCycles.vi determines the number of cycles in the oscillator output data array (Chan0_in) by checking for sign changes. It then increases or decreases the sample rate (for a ...
