APPARATUS FOR EFFICIENT FREQUENCY MEASUREMENT |
摘要 |
An apparatus for efficient frequency measurement (JKLMTM) which provides precise and accurate measurement of a single input tone frequency and/or multiple separable input tone frequencies. Tone separability can be achieved by proper selection of the parameter N, the sample length of the DFT/FFT. |

1. An apparatus for efficient frequency measurement, comprising:
a signal conditioner having an input and an output; an analog-to-digital converter having an input and an output; a parser having an input and an output; a Fourier Transformer having an input and an output; a selector having an input and an output; and a processor having a signal input, an output, and a coefficient input, wherein,
an external analog signal to be measured is input into said input of said signal conditioner;the output of said signal conditioner is connected to the input of said analog-to-digital converter;the output of said analog-to-digital converter is connected to the input of said parser;the output of said parser is connected to the input of said Fourier Transformer;the output of said Fourier Transformer is connected to the input of said processor and to the input of said selector; and whereinthe output of said selector is connected to the coefficient input of said processor. |
