A television signal processing circuit includes an audio/video (AV) signal generating circuit, an intermediate frequency (IF) mixer, a first filter, a radio-frequency (RF) mixer, a second filter and a digital-to-analog converter (DAC). The AV signal generator generates a digital AV signal. The IF mixer converts the digital AV signal to an IF AV signal. The first filter filters the IF AV signal to generate a filtered IF AV signal. The RF mixer converts the filtered IF AV signal to an RF AV signal. The second filter filters the RF AV signal to generate a filtered RF AV signal. The DAC converts the filtered RF AV signal to an analog AV signal and transmits the analog AV signal to an antenna.

Audiovisual signal processing circuit and associated television signal processing method

An audio processing apparatus including an audio phase detecting device and an adjusting device is provided. After detecting a phase relationship between a first channel signal and a second channel signal, the audio phase detecting device generates a phase control signal. The adjusting device is coupled to the audio phase detecting device and used for selectively adjusting the first channel signal according to the phase control signal.

Audio processing apparatus and related method

A dynamic element matching method and system thereof is provided. The method includes grouping a plurality of switches into a plurality of groups; allocating a plurality of to-be-turned-on switches of the switches for an input signal to the groups; and maintaining a switch activity of each of the groups at a predetermined value. Accordingly, mismatch noise and harmonic noise are effectively reduced.
