Patent JP-H05153089-A (JP)
Title: Telephone set
Inventor: NISHIO HITOSHI
IPC: H04K1/02
Filed: 1991-11-29
Abstract: PURPOSE:To make the wire tapping of call contents difficult by adding a noise signal to a voice signal and permitting information on the added voice signal itself to be transmitted simultaneously while incorporating it independently in control data. CONSTITUTION:At a transmission side, the voice signal from a general telephone line comes into the voice processing circuit line control circuit 15 of a master set. DTMF(dual tone multi frequency) generating circuit 22 is utilized by the introduction of CPU 23 at the master set side so as to generate an FSK (frequency shift keying) signal, for example, which is the harsh signal and, then, the voice signal is added. Information on noise added on control data in a moment when the voice signal enters into a conversation channel or periodically is simultaneously added and, then, the voice signal is transmitted to a slave set. Moreover, added noise signal is made to change by the control of CPU 23 at every fixed time in accordance with a program with a phase and a frequency previously set. At the reception side, noise added at the transmission side is removed.
