Pure Sine Wave Oscillator Circuit Diagram. It can gives high purity sine wave output down to low frequencies with minimum circuit complexity. Ic cd4047 has built in facilities for astable and bistable multivibrators.
Ic cd4047 has built in facilities for astable and bistable multivibrators. This circuit as known as amplitude stabilized sine wave oscillator. It passes the high dc voltage for specified amounts of time so that the average power and rms voltage are the same as if it were a sine wave.
Thus a sine wave may be the input to a device or circuit with the output harmonics measured to determine the amount of distortion.
A modified sine wave can be seen as more of a square wave than a sine wave. We can also use ic 4047 to generate sine wave. Please refer the detailed explanation about this stage in this pure sine wave article. This is still a great chip.
