The Average Response Computer (sometimes referred to as the ARC-1) was not actually a computer (as implied by the name), but a digital transistor data recording/analysis device. It took a number of data samples, provided by an analog-to-digital converter, and summed and averaged them (hence the 'computer'), to remove the noise. It was built at Lincoln Laboratory in 1958. Its importance was as a predecessor to the LINC (see the tale in the Clark history, below).
