The MX102 is a single-chip device to extract single periodic signals from very high random-noise environments.
Using patented autocorrelation techniques the MX102 will enhance the input signals signal-to-noise ratio by as much as 8.5dB and provide a digital output signal centered at four times (x4) the input frequency.
The amplitude of non-periodic components of the signal is substantially reduced. The patented autocorrelator compares the incoming signal to itself; the more elements of the waveform that are seen as periodic, the higher the energy at the microcircuit output.
