Each return pulse is integrated sequentially by a single detector and processed by heterodyne reception and synchronous demodulation.
Armstrong eventually sold his superheterodyne patent to Westinghouse, who then sold it to RCA, the latter monopolizing the market for superheterodyne receivers until 1930.[5]

Armstrong realized that this was a potential solution to the "short wave" amplification problem, since the beat frequency still retained its original modulation, but on a lower carrier frequency.
Armstrong eventually sold his superheterodyne patent to Westinghouse, who in turn sold it to the Radio Corporation of America (RCA), the latter monopolizing the market for superheterodyne receivers until 1930.[9]
