Mike: Nearly every analog instrument uses the 4-20 mA loop. Field transmitters, positioners, and variable frequency drives ...

Discrete Fourier Transform (DFT) and Fast Fourier Transform (FFT) are core components in the field of signal processing. However, in the existing research, there is no fully analog circuit that can ...

Three-stage RC phase shift oscillation circuit is common as a low-frequency oscillation circuit for its low cost and high stability. Due to the output impendence of the operation amplifier or ...
