Title: Dialling tone selector for atomic call up of telephone numbers - has output of detector circuit at level of supply charging capacitor
IPC: H04Q1/446
Filed: 1975-11-13
Abstract: Telephone circuit dialling tone selector is intended for automatic call-up telephone numbers. In this system the recognition time of the dialling tone is not much longer than the pulse duration of the slowest periodic engage tone. The dialling tone is supplied to the input (1) of the circuit. The output (4) of the dialling tone detector is normally at the voltage level offered at the supply voltage terminal (3). The circuit makes use of the fact that the dialling tone is continuous whereas the engaged tone is an interrupted signal. The dialling tone is used to charge a capacitor to a voltage level which will act as the detection value. The capacitor is discharged via a semiconductor circuit which is controlled by differential pulses formed from the leading edges of the rectified dialling tone signals. The charge-up time of the capacitor to the detection value is longer than the longest interrupted pulse duration.
