I have a signal with relation A sinw1t cos(phi-w2t). w1 = 50Hz and w2=1khz. I need to extract carrier from the product. I tried using Band pass filter with cut off 750 hz and 1500 hz. I am unable to get the second term properly. Tried different combinations, but with little success. Help required to get the right method of extraction.
