It generates an oscillatory output signal without having any input source
A Wien bridge oscillator is a type of electronic oscillator that generates sine waves without having any input source. It can output a large range of frequencies. The bridge comprises four resistors and two capacitors. The circuit is based on a network originally developed by Max Wien in 1891. At that time, Wien did not have a means of developing electronic gain so a workable oscillator could not be realized. The modern circuit is derived from William Hewlett's 1939 Stanford University master's degree thesis. Hewlett, along with David Packard co-founded Hewlett-Packard. Their first product was the HP 200A, a precision sine wave oscillator based on the Wien bridge. The 200A is a classic instrument known for its low distortion. The frequency of oscillation is given by:
Change one or more of the values of the inductance or capacitance of one or more of its legs.
