SYSTEM FOR COMPENSATING FREQUENCY LEVEL OF SPEAKER |
摘要 |
A system for compensating a frequency property which is changed according to the level variation of input signal is provided to compensate distortion factor. The system comprises: a level sensor(80) for detecting an output level of a main amplifier(60); a speaker(70) connected to an output terminal of the main amplifier(60); and a microcomputer(90) having a ROM(read only memory)(100) for reading a value of FIR filter and supplying the value to a first and second FIR filter(51,52), thereby compensating a distortion factor of the speaker(70).
