METHOD FOR PAGING A TELEPHONE AND AN APPARATUS THEREOF, ESPECIALLY CONCERNED WITH CLEARLY TRANSMITTING PERSONAL VOICE INFORMATION BY MODULATING A VOICE SIGNAL INTO A PLURALITY OF RF SIGNALS TO BE APPROPRIATE FOR A VOICE FREQUENCY BAND USED FOR A TELEPHONE AND SYNTHESIZING AND AMPLIFYING THE RF SIGNALS, AND DIVIDING THE RECEIVED RF SIGNALS SO AS TO BE RESTORED TO THE VOICE SIGNAL

摘要

PURPOSE: A method for paging a telephone and an apparatus thereof are provided to transmit information included in a voice signal at the maximum by dividing personal voice information so as to be appreciated for a voice frequency band used in a telephone, and then transmitting the information. CONSTITUTION: A microphone(11) receives input of a voice. A pre-amplifier(12) amplifies the voice signal inputted from the microphone(11). A low pass filter(13) and a high pass filter(14) decompose the voice signal to make the voice signal appropriate for a voice frequency band used for a telephone. A plurality of RF modulators(15) connected with the low pass filter(13) and the high pass filter(14) modulate the voice signal. An RF signal synthesizer(16) synthesizes RF signals. An RF amplifier(17) amplifies the synthesized RF signal. A channel divider divides the RF signal into a plurality of RF signals. A demodulator demodulates the divided RF signals into a voice signal band. A frequency shift modulator shifts frequency to synthesize the demodulated RF signals into one signal. A signal synthesizer synthesizes the demodulated RF signals into one signal for outputting the signal to a line level.
