WebMatched filter is a theoretical frame work and not the name of a specific type of filter. It is an ideal filter which processes a receivedsignal to minimize the effect of noise. Hence, it maximizes the signal to noise ratio (SNR) of the filtered signal. WebHomodyne demodulation is a convenient technique for signal detection in interferometric sensors. The demodulation process is typically developed using analog circuits. However, to improve the performance of the demodulator, a digital system must be employed. In this study, we developed an optical fiber sensor by combining: (a) a Michelson interferometer, … flag of honduras
