7 / 14 page 1 fH = 2 π C 30k / / 30k (Hz) C = External capacitor connected to Pin 5 275 Audio ICs BA3430S / BA3430F / BA3430FS FMute detection circuit (1) Mute detection based on noise and music signals The signals of each block in the mute detection circuit are shown in the diagram below. (2) Sensitivity switch amplifier circuit The noise level and signal frequency of the tape differ during playback and fast forward. Therefore, this signal amplifier includes a circuit for switching the detection fre- quency and gain for playback and fast forward. (1) Sensitivity switch circuit This circuit switches the detection frequency and gain for playback and fast forward. A 10k Ω or less resistor must be connected to the input pin to limit the input current. The electrolytic capacitor be- tween the input pin and ground is for preventing incorrect detection. Without this capacitor, sensitivity switch noise may cause incorrect detection of songs. Input switch truth table 2) Input low pass filter High frequency noise increases during fast forward. This filter reduces high frequency noise. It consists of an inter- nal 30k Ω resistor which combines the left and right equal- izer output and an external capacitor connected to Pin 5. The cutoff frequency of the low pass filter fH is |
