Bill had the innovative, elegant and practical idea of using a light bulb in a Wein bridge oscillator circuit to solve the problem of how to regulate the output of the circuit without causing distortion. The Model A was HP ‘s first product. Retrieved from ” https: From Wikipedia, the free encyclopedia.

It used the Wien bridge oscillator circuit, that had been the subject of Bill Hewlett auudio Masters thesis. The latter is a key technique for achieving a low distortion oscillator. Earlier, Meacham had used light bulbs in bridge ho to stabilize and linearize oscillators in It was a low-distortion audio oscillator used for testing sound equipment. Views Read Edit View history. Uses tungsten lamp to balance bridge. By the clever use of the light bulb, Bill was able to simplify the circuit, improve the oscillator’s performance and reduce the price.
