Draw a labeled block diagram of sine wave generator and state function of each block.

Function Generator:

This instrument can deliver sine, triangular & square waves with frequency range of 0.01 Hz to 100 kHz.

The frequency control network is governed by a frequency dial on the front panel of the instrument

The frequency control voltage regulates two current sources.

The upper current source supplies a constant current to the integrator whose output voltage increases with time.

The voltage comparator multi-vibrator changes state at a predetermined level on the positive slope of the integrator’s output voltage.

The lower current source supplies a reverse current to the integrator so that its output voltage reaches a predetermined level on the negative slope of the integrator’s output voltage.
