Abstract
A frequency shift keying digital signal receiving apparatus includes a detecting portion detecting a new signal on the basis of a signal, from which a correlated ambient noise is filtered out by an adaptive filter, a holding portion holding a first electric power for the signal received before a new signal is detected, a calculating portion calculating a second electric power for the signal received after the new signal is detected, a comparing portion comparing levels of the first and second electric powers, a selector selecting the signal, from which the correlated ambient noise is filtered out, when the first electric power is higher than the second electric power and selecting the signal bypassing the adaptive filter when the first electric power is lower than the second electric power, and a demodulating portion demodulating a desired signal on the basis of the signal selected by the selecting portion.
