Abstract
A voice band correcting apparatus in which the signal level of limit bands is amplified by a correction filter, the signal level of a correction signal supplied is compared by a level detector to a preset level, and the result of decision is sent as level information to a coefficient controller, where the signal level is adjusted in a controlled manner. The high-quality broadband signal may be obtained on correction without degrading the quality of a communication signal ascribable to excess amplification.
Claims21
A band correcting apparatus comprising:
- a corrector receiving with an input signal limited in frequency band for correcting the input signal with respect to a signal level of each limit band and outputting a corrected signal;
- a monitor for monitoring whether or not the signal level of the corrected signal reaches a preset level;
- and
- a level adjustor for adjusting the signal level responsive to level information from said monitor.
A band correcting apparatus comprising:
- a band splitter for splitting a band of an input signal into a plurality of limit bands;
- a corrector for correcting a signal level of the bands obtained on splitting for outputting correction signals;
- and
- an analog converter for converting each of the correction signals into analog signals.
