Techniques for suppressing spurs in a receiver are described. A processor (e.g., within a wireless device) receives digital samples for a desired signal having a spur located within the bandwidth of the desired signal. A spur is an undesired signal that may be generated internally at the receiver or may come from an external interfering source. The processor filters the digital samples to suppress the spur and provides output samples having the spur suppressed. The processor may detect for the spur, e.g., by performing an FFT on the digital samples and examining the spectral response. The processor may filter the digital samples with a notch filter having an adjustable notch frequency and/or an adjustable notch bandwidth. For example, the notch frequency may be set based on the frequency of the spur, and the notch bandwidth may be set based on the amplitude of the spur.
