Wien Bridge Oscillator Output Waveform. Obtain the sine wave at the output. Magnitude of the loop gain a v β 1 where a v amplifier gain and β feedback gain.
These can all be useful alternatives to crystal clocks which can radiate noise at multiple harmonics and can even act like center fed patch antennas if not laid out properly. Phase shift around the loop must be 360 or 0. Oscillator circuit must satisfy the following two conditions known as barkhausen conditions.
The output from your wien bridge oscillator will be a smooth curve just like the sathorn narathiwas intersection in bangkok.
One of the simplest sine wave oscillators which uses a rc network in place of the conventional lc tuned tank circuit to produce a sinusoidal output waveform is called a wien bridge oscillator. Wien bridge oscillator is an audio frequency sine wave oscillator of high stability and simplicity. The output from your wien bridge oscillator will be a smooth curve just like the sathorn narathiwas intersection in bangkok. It s the same of waveform that is output from ac electricity in homes.
