The detector is responsive to a modulated intermediate frequency (IF) or radio frequency (RF) signal for producing four sample signals spaced at 90.degree. one-quarter IF (or RF) cycle apart, the first and third sample signals corresponding to the amplitude of the IF signal and its negative value, respectively, the stream of such sample signals corresponding to the inphase component of the IF signal; the fourth and second sample signals corresponding to the amplitude of the IF signal and its negative value, respectively, the stream of such sample signals corresponding to the quadrature component of the IF signal.
