Adjustable signal equalization device and adjustment method thereof
An adjustable signal equalization device includes an equalizer circuitry, an analog-to-digital converter (ADC), a calculation circuitry, and a comparator circuitry. The equalizer circuitry has a transfer function, and processes an input signal based on the transfer function to generate an output signal. The ADC generates a digital signal according to the output signal. The calculation circuitry performs an accumulation according to the first digital signal to generate a first accumulated value and a second accumulated value, and generates a first detection signal and a second detection signal according to the first accumulated value and the second accumulated value. The comparator circuitry compares the first detection signal with the second detection signal to output a control signal to the equalizer circuit if the first detection signal is different from the second detection signal, in order to adjust the transfer function.
