A Decision Feedback Equalizer (DFE) with programmable taps includes a summer configured to receive a DFE input signal. Delay elements are coupled to the summer. The delay elements are connected in series. Each delay element provides a respective delayed signal of an input signal to the delay element. A weight generator is configured to provide tap weights. The DFE is configured to multiply each tap weight to the respective delayed signal from the respective delay element to provide tap outputs. Each tap output is selectively enabled to be added to the summer or disabled based on a first comparison of a first threshold value and each impulse response or each tap weight corresponding to the respective tap output, where the impulse response is the DFE input signal in response to a pulse signal transmitted through a channel.
