Title: Dialling pulse generator for telephone systems - uses two presettable counters to define pulse duration and intervals
Inventor: JOERGENSEN TORBEN
IPC: H03K3/78
Filed: 1976-02-25
Abstract: The dialing pulse generator, for telephone equipment, has a clock generator and counter to fix pulse duration, pulse interval and the distance between pulse trains. The final output signals are produced by a bistable flip flop. A second counter acts with the first counter such that they are alternately actuated. The bistable flip flop controls the changeover from one counter to the other. Both counters can be preset so that new times can be incorporated easily: all that needs to be permanently retained is the number of pulses per pulse train. This avoids the need for memory capacity and therefore reduces costs.
