Methods and systems for processing television signals are disclosed herein, and may comprise communicating analog and digital intermediate frequency (IF) signals via a single processing path that couples a TV radio frequency (RF) tuner to an IF demodulator and/or to a decoder, that processes said analog and digital IF signals. The analog and digital IF signals may be filtered via a surface acoustic wave (SAW) filter, for example. The filtered analog and digital IF signals may be amplified. The amplified filtered analog and digital IF signals may be received. The amplified filtered analog and digital IF signals may be IF demodulated by the IF demodulator to generate an IF demodulated output signal. An audio portion of the IF demodulated output signal may be decoded via a BTSC decoder, for example.
