The embodiments described herein provide devices and methods that facilitate improved performance. In one embodiment, an input device comprises a processing system, a transmitter sensor electrode, and a receiver sensor electrode, where the transmitter sensor electrode and the receiver sensor electrode are capacitively coupled. The processing system is configured to receive a resulting signal from the receiver sensor electrode, where the resulting signal includes responses that correspond to the transmitter signal. The processing system is further configured to separately accumulate, for each cycle of the transmitter waveform, a first portion and a second portion of the resulting signal to respectively produce a first accumulation and a second accumulation, wherein the first accumulation is used for determining user input to the input device and the second accumulation is used for determining interference, and wherein the first portion and the second portion are non-coterminous.
