Estimating the term…
A finite impulse response (FIR) filter including an input of the FIR filter that receives an RF input signal, a clock input configured to receive a clock signal, an output of the FIR filter that provides a filtered output signal, a plurality of signal paths including a plurality of sample-and-hold circuits and a plurality of multipliers arranged in parallel, each signal path including a respective sample-and-hold circuit and a respective multiplier being configured to receive the RF input signal and the clock signal to provide a modulated output signal, an adder configured to receive n modulated output signals from the plurality of signal paths and combine the n modulated output signals to produce the filtered output signal, and a controller.
A finite impulse response (FIR) filter comprising:
An analog cancellation module including a finite impulse response (FIR) filter for use in a transceiver system, the analog cancellation module comprising:
The analog cancellation module of claim 18, wherein the FIR filter further includes a plurality of switches coupled to the controller and configured to selectively connect and disconnect at least one signal path of the plurality of signal paths.
