| Abstract: | This paper reports a circuit for sampling multiple frequency signals automatically which composes of a signal conditioning circuit with multiple analogue switch and of a frequency acquisition board. Commercialized programmable digital input/output and timer board is modified for frequency acquisition board which is cheap and of the easy-to-use advantage. Thecircuit can meet the experiment requirements. |
