7 Two channels demodulation In many technical applications we need to measure both components (E x, E y ) of the input signal. To do this most of the modern lock-in amplifiers are equipped by two demodulators. E in =E o sin(wt+j) to E x channel y sin(wt) E y j x E x to E y channel cos(wt) 3/12/2013 Physics 403 Spring
