Circular Regression in a Dual-Phase Lock-In Amplifier for Coherent Detection of Weak Signal

Lock-in amplification (LIA) is an effective approach for recovery of weak signal buried in noise. Determination of the input signal amplitude in a classical dual-phase LIA is based on incoherent detection which leads to a biased estimation at low signal-to-noise ratio. This article presents, for the...
