IPC: H04M11/00
Filed: 1988-09-29
Abstract: PURPOSE:To attain accurate detection of a dial pulse signal by obtaining a position having a large correlation between an impulse response and an input signal as a make/brake position. CONSTITUTION:A dial pulse signal detector 3 consists of a linear difference calculation section 30, a correlation calculation section 31, and a pulse retrieval section 32. Through the constitution above, the impulse response R of a synthesis filter is decided in advance and a band pass filter having a transmission characteristic as that of an average channel is used as the synthesis filter. The correlation phixr between the linear difference signal X of the input signal Y and the impulse response R obtained by the calculation section 30 is obtained by the calculation section 31 and the correlation phixr is used to retrieve a pulse by the retrieval section 32. That is, the pulse is retrieved repetitively while the level of the pulse is over a prescribed threshold level decided in response to the level of the initial pulse and when it reaches a prescribed position, it is used for the make or brake position of the dial pulse signal.

Title: Automatic output switching circuit
Inventor: KOJIMA TOMOYUKI
IPC: H04N5/60
Filed: 1984-11-22
Abstract: PURPOSE:To obtain a TV set by which the output of a stereo or a MONO broadcast is possible to be outputted at an output terminal by providing a means to turn over a function change over switch to a stereo demodulation's side when SAP broadcast isn't executed by a noise component and a discrimination output. CONSTITUTION:In terms of a detection signal, 'H' level is outputted when SAP signal is generated, and in terms of the noise component, a nozzle detector is not actuated when a signal is given and the output of detection becomes 'H'. When SAP broadcast isn't made, the output of SAP carrier detector 10 becomes 'L' or 'H' because noise is detected by error. The output of a noise detector 11 becomes 'L' to detect the noise. Therefore, the output of AND circuit 12 becomes 'L' and a switch 15 is turned on. The output of an inverter 13 becomes 'H', and a switch 14 is turned off. An output signal from matrix 7 is outputted to the output terminal independently to a function change over switch 9. Thus, as long as either the SAP broadcast and the stereo broadcast exists, a sound 1 signals is outputted to the outputted of the TV set to make it easy to operate it.
