The BBC Designs Department produced a successful electronic alternative which sounded realistic and was capable of being used for a broad range of sounds which could not be made naturally.
The versatile "wobbulator" was a sine-wave oscillator that could be frequency modulated. It consisted of a metal box with a few switches and one very large knob that could sweep the entire frequency range.
Fragments of recorded sounds were manipulated and then spliced together to form compositions and tape loops sometimes several metres long.
The ring modulator works by taking two inputs and multiplying them together. In the original Ring Modulator a tape loop with a 30Hz sine wave tone was combined in real time as an actor spoke into a microphone. The diodes in the machine also gave the effect its characteristic distortion.
*The ring modulator is best known as the device used to create the terrifying voices of the Daleks and the Cybermen in Dr. Who.
