Abstract
An organ keyer system, especially a keyer system operated by logic level signals, such as occur in multiplexing. The keyer system herein described is especially intended for manufacture by large scale integration techniques, and is designed to provide for the controlled attack and decay of the keyed signal without the use of timing components, such as resistor and capacitors, external to the integrated circuit.
