Abstract
A circuit applied to a display apparatus includes a front-end circuit, a conversion circuit and an impulsive interference detection circuit. The front-end circuit converts an analog input signal into a digital input signal. The conversion circuit, coupled to the front-end circuit, converts the digital input signal from a time domain to a frequency domain to generate a frequency-domain signal. The impulsive interference detection circuit, coupled to the conversion circuit, detects a noise intensity of the frequency-domain signal to generate a detection result, which is used to determine whether the analog input signal has impulsive interference.
