摘要：A pha locked loop is disclod which subtracts an estimated signal from an input signal and operates upon the residual signal. The residual signal is demodulated and applied to a controlled oscillator which produces feedback signals approximately the sine and cosine of the input signal. The cosine feedback signal is multiplied by the residual signal who resultant signal is a frequency correction signal. The sine feedback signal is multiplied by the residual signal for multiplication again by the sine feedback signal to produce the estimated signal which is amplitude and frequency controlled. This signal is then subtracted from the input signal to reduce the residual signal to near zero.
