Abstract
A digital demodulating apparatus comprises circuit components constituting a tuner that applies channel select processing to a received signal, and a demodulator that demodulates the signal to which the tuner has applied channel select processing; a power supply unit that supplies power to each circuit component; a reception condition detecting unit that detects a reception condition when the tuner receives the signal; a power adjusting unit that adjusts the power to be supplied to each circuit component by the power supply unit, on the basis of a result of the detection by the reception condition detecting unit; a fading environment estimating unit that estimates a fading environment when the tuner receives the signal; and a power controlling unit that controls the power adjusting unit on the basis of a result of the estimation by the fading environment estimating unit so that the number of times of adjustments of the power by the power adjusting unit per unit time changes in accordance with the variability of the reception condition.
