ABSTRACT:
A system for spur cancellation comprises an input, an output, a memory, and a summer. A value corresponding to an energy level of a spur is stored in the memory. The summer is configured to receive an input signal from the input, to receive the value from the memory, to subtract the value from the input signal, and to convey an output signal to the output. The output signal is a difference of the value subtracted from the input signal.
