Patent ID: 8401116

Claim:
An RF receiver comprising: an amplifier configured to receive an RF signal over an input bandwidth and to provide an amplified RF signal; an equalizer circuit connected to the amplifier to receive the amplified RF signal and configured to provide an equalized RF signal; a converter module connected to the equalizer circuit and including an analog to digital converter configured to convert the equalized RF signal to a digital signal; and a digital signal processing module connected to the converter module and configured to process the digital signal to provide a plurality of channels at an output of the receiver, wherein the digital signal processing module is further configured to process the digital signal to determine a measure of tilt in the RF signal across the input bandwidth and is connected to the equalizer circuit to provide a control signal for adjusting the measured tilt, wherein the equalizer circuit comprises a network of switchable impedance elements configured to provide a selectable degree of tilt applied by the equalizer circuit to the amplified RF signal under control of the control signal from the digital signal processing module.
