Title: Dtmf receiver
Inventor: TANAKA SHIGENOBU
IPC: H04M11/00
Filed: 1993-04-13
Abstract: PURPOSE:To provide the DTMF receiver used for an automatic answering telephone set provided with a remote control function and capable of saving power consumption and curtailing the number of operation processing steps. CONSTITUTION:A DTMF signal received through a telephone line is separated by a group separation filter circuit 1 and a limiter circuit 2 detects a signal level from an output voltage of the group separation filter circuit 1. On the other hand, a register circuit 6 stores selection control information for a frequency to designate a DTMF signal subject to reception processing. Thus, a band pass filter circuit 3 passes through a group unit output of the limiter circuit based on selection control information of the register circuit 6. Furthermore, an output of the band pass filter circuit 3 is rectified by a rectifier circuit 4 and the output of the rectifier circuit 4 is decode-processed by a logic circuit 5 and the reception time is measured.
