| Abstract: | The relationship among the bandwidth of frequency selective amplifier, the response time and the signal-to-noise ratio in the photoelectric detecting system is analyzed. A method for the determination of bandwidth in the preliminary design stage is suggested according to the required response time and optimal signal-to-noise ratio. |
