Abstract
A method for processing an input signal is disclosed. The method includes receiving an input signal. The method also includes applying a first transfer function to the input signal to produce a first signal, wherein the first transfer function exhibits a high pass characteristic. The method further includes applying a second transfer function to the input signal to produce a second signal, the second transfer function exhibiting a low pass characteristic.
Claims27
A method for processing an input signal, comprising:
- receiving an input signal;
- applying a first transfer function to the input signal to produce a first signal, the first transfer function exhibiting a high pass characteristic;
- and
- applying a second transfer function to the input signal to produce a second signal, the second transfer function exhibiting a low pass characteristic.

A low-pass filter tap, comprising:
- a resistor having a first resistor terminal and a second resistor terminal;
- and
- an inductor comprising a first inductor terminal coupled to the second resistor terminal and a second inductor terminal;
- wherein the low-pass filter tap receives an input signal and produces an output signal comprising at least a portion of the input signal.
1 more element
An integrated circuit, comprising:
- an in-band tuner operable to receive a first signal comprising a plurality of content channels and further operable to extract information from a selected content channel;
- and
- an amplifier operable to receive a second signal comprising a plurality of data channels, the amplifier further operable to amplify the second signal and communicate the second signal to an out-of-band tuner.
An apparatus, comprising:
- a low-pass filter tap comprising at least one resistor, at least one inductor, and at least one capacitor, the low-pass filter tap operable to apply a first transfer function to an input signal to produce a first signal and further operable to apply a second transfer function to the input signal to produce a second signal, wherein the first transfer function exhibits a high pass characteristic and the second transfer function exhibits a low pass characteristic;
- an integrated circuit, comprising:
- an in-band tuner operable to receive the first signal and to extract content from a selected channel of the second signal;
- and
- an amplifier operable to amplify the second signal and further operable to communicate the second signal to an out-of-band tuner.
