Hello, I'm trying to amplify a low-frequency signal which has a short peak of just some microvolts. What amplifiers would you recommend me for this application? Thanks in advance. |

Hi lcruz, Have you tried doing something like the single transistor amplifier we use in the sound meter video? You probably have some 2n7000s around and can give it a quick test to see if it will suit your needs. Humberto |

Humberto, Sounds like a perfect way to amplify the signal. I just bought a couple of 2N3904 NPN and also got some 2N700 from some past projects :) The signal I am talking about is between 5Hz and 50Hz, and its amplitude is maybe just some microvolts (μV). Will this work for me? Thank you. |

Make sure and use capacitors to quiet any noise at that level random noise could be confused for a actual signal. Ra;ph |
