In one example system, switching circuitry can be used to selectively couple each of the sense lines of a touch sensor to a positive terminal or a negative terminal of a sense amplifier based on the values of the elements of a matrix. The touch signals can be amplified and converted into digital form using a single sense amplifier and an ADC before being decoded using decoding circuitry. The decoding circuitry can decode the digital encoded touch signals by multiplying the digital encoded touch signals by each column of an inverse of the matrix used to encode the touch signals. The result of the decoding can be a set of signals that are representative of the touch signals output by the touch sensor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch receiving channel re-use scheme with receiver signal coding","description":"Systems and processes for encoding and decoding touch signals output by a touch sensor are provided.
