摘要： A broadcast receiver includes a tuner circuit and a demodulator circuit. The tuner circuit tunes a radio frequency (RF) signal to output an intermediate frequency (IF) signal. The demodulator circuit demodulates the IF signal from the tuner circuit and outputs a command signal based on the quality of the IF signal, for changing a take over point (TOP) value, preset in the tuner circuit, at which one amplitude gain control (AGC) stopping and another taking over. A method for regulating a broadcast receiver is also disclosed herein.

摘要： A method for determining a sound standard for an input sound signal includes the following steps. Firstly, the input sound signal is filtered to obtain a first filtered signal corresponding to a first frequency and a second filtered signal corresponding to a second frequency. Next, the first filtered signal is frequency-demodulated to obtain a first demodulated filtered signal, and whether the input sound signal contains a FM analog component corresponding to the first frequency is determined accordingly. Next, the second filtered signal is decoded according to a digital sound standard to obtain a bit stream. Then, the bit steam is interpreted according to the digital sound standard, and whether the input sound contains a digital component corresponding to the digital sound standard is determined accordingly. Then, whether the input sound signal matches one of known sound standards is determined based on the determined results above.
