PURPOSE: To illustrate a voltage-controlled frequency device.
DESCRIPTION: The oscillator at the left produces a slowly varying voltage which is input into the VCG (voltage-controlled generator) input of the oscillator on the right. The frequency of the second generator is controlled by the VCG signal. T he loudspeaker is driven directly by the output of the second generator.
REFERENCES: (PIRA unavailable.)
EQUIPMENT: Two Wavetek generators, loudspeaker.
SETUP TIME: 5 min.
