This thesis is present an UHF REMOTE CONTROL by used radio wave UHF band ( about 304 Megahertz ) . The MC 145026 will encode mine bits of information and serially transmit data ( 0,1, open ) to allow 19683 different codes. The decoders will receive the 9 bit word and will interpret some of the bits as address codes and some as data. When the transmitter sends address codes that match that of the receiver. A valid transmission output will go high on decoder when they recognize an address that matches that of the decoder.
