milstar: 1941: First (vacuum tube) op-amp An op-amp, defined as a general-purpose, DC-coupled, high gain, inverting feedback amplifier, is first found in US Patent 2,401,779 "Summing Amplifier" filed by Karl D. Swartzel Jr. of Bell labs in 1941. This design used three vacuum tubes to achieve a gain of 90dB and operated on voltage rails of ±350V. ###################################################### It had a single inverting input rather than differential inverting and non-inverting inputs, as are common in today's op-amps. Throughout World War II, Swartzel's design proved its value by being liberally used in the M9 artillery director designed at Bell Labs. ######################################################################### This artillery director worked with the SCR584 radar system to achieve extraordinary hit rates (near 90%) that ####################################################################### would not have been possible otherwise.[3] ########################### http://en.wikipedia.org/wiki/Operational_amplifier

milstar: Important simplifications result from selecting the sampling frequency fs to be equal to 4 fc [1][2]. ====================== The quadrature sinusoids can then be reduced to the trivial sequences {1, 0, -1, 0, . . .} and {0, -1, 0, 1, . . .}, eliminating the need for digital multipliers or the synthesis of the quadrature signals. http://accelconf.web.cern.ch/Accelconf/p95/ARTICLES/RPQ/RPQ02.PDF
