Abstract
A television receiving system is disclosed, comprising an input terminal, a down-converter, an amplifier, an analog-to-digital converter (ADC), a demodulator, and an isolation circuit. The input terminal receives an RF signal. The down*converter, coupled to the input terminal, converts the RF signal to an intermediate frequency (IF) signal. The amplifier, coupled to the down-converter, amplifies the IF signal. The analog-to-digital converter, coupled to the amplifier, converts the amplified IF signal to digital data. The demodulator, coupled to the ADC, processes the digital data to generate baseband data. The isolation circuit, coupled between the amplifier and ADC, isolates the amplified IF signal from being affected by interference induced by the ADC.
