`The present invention relates to the transmitting circuit and wireless headphone receiving circuit of the
`code division type sending and receives the signal to the code division type. The invention includes the
`codec part (7) encoding the signal applied from the signal source (8), the central control modem unit (6), and the base band part (5) and
`it is augmented the signal outputted in the base band part (5) and it filters and the gain of the signal is controlled and it transmits to the
`antenna (A). The central control modem unit (6) prints out the output of the codec part (7) to the input and it error-corrects and diffuses
`the band of the signal. The base band part (5) prints out the output of the central control modem unit (6) to the input and it converts into
`the intermediate frequency and outputs the transformed signal. And the wireless headphone receiving circuit which controls the gain while
`being augmented the signal in which the wireless headphone receiving circuit of the code division type is applied from the wirelessly
`through the antenna (A) and filtering and outputs the audio signal to the output unit (9) comprise the base band part (5): central control
`modem unit (6): codec part (7): which decodes the audio signal it prints out the output of the central control modem unit (6) to the input
`and the amplifier (1c) which signs to the input and outputted in the codec part (7) it amplifies and outputs the amplified audio signal to
`the output unit (9). Removes the bug fixing and pseudorandom code it prints out the output of the base band part (5) to the input it
`processes as the intermediate frequency it signs to the input the gain is controlled.
