CIRCUIT FOR THE PROCESSING, TRANSMISSION AND ACOUSTIC REPRODUCTION OF DIGITALIZED TONE FREQUENCY SIGNALS

摘要

Digitized audio-frequency signals are processed in a signal processor (SP) together with digital control signals and pass through a wireless infrared transmission link (I) whose receiver (E) and a following power amplifier (V) are incorporated in a loudspeaker box (B). The audio-frequency signals are coded in a protected code and are fed first to a code-conversion/error-correction processor (CP), then to the signal processor (SP), and then to an RF modulator (M) which drives the transmitter (S) of the transmission link (I). In a modification, the code-conversion/error-correction processor (CP) and the signal processor (SP) are disposed within the loudspeaker box (B'), so that errors arising on the transmission link (I) can be compensated for.
