Patent ID: 7064691

Claim:
A communication apparatus comprising: (a) a first A/D converter for converting a first analog signal to be sent into a first n-bit digital signal composed of “0” and “1”; (b) a first encoder which is connected to the first A/D converter and that encodes all bit column patterns composed of said first n-bit digital signal, by correlating with a first m-bit (m>n) bit column pattern, in which the number of “0” is equal to the number of “1”, in a one-to-one relationship; (c) first m data buses which are connected to the first encoder and that send the first m-bit bit column pattern obtained by the first encoder; (d) a transmission memory connected to the first data buses; (e) second m data buses which are connected to the transmission memory and that send said first m-bit bit column pattern; (f) a first decoder which is connected to the second data buses, that receives the first m-bit bit column pattern sent through the second data buses and decodes the first m-bit bit column pattern to the corresponding second n-bit transmission data; (g) a first D/A converter which is connected to the first decoder and that converts said second n-bit transmission data into a second analog signal; (h) a transmitter signal processor connected to the first D/A converter; and (i) a wireless transmitter connected to the transmitter signal processor.
