Abstract
A signal coding system capable of high efficiency, high quality signal coding is provided. Digital signals represented in the time domain are divided into set time interval data units and output. One output is converted to a digital signal represented in the frequency domain, and the other is output as-is. The energy dispersion of the digital signal represented in the frequency domain is compared with that of the digital signal represented in the time domain, and the digital signal having the least energy dispersion is coded. This coded digital signal is then multiplexed with an identification signal to identify it as a frequency domain or time domain signal, and the resulting multiplexed signal is output.
