Abstract
A signal power coefficient and a noise power coefficient are calculated for each channel, using parameters which have been optimized up to a small error value by an optimizing means, then using the thus-calculated signal power coefficient and noise power coefficient, there are determined a signal power and a noise power for each channel, and the signal power and the noise power thus determined are displayed on one and same display screen channel by channel.
