With this circuit, from an old operational datasheet, it is possible to measure the CMRR, rejection in common mode of an operational one. The power supply must be symmetrical.
The purpose of this circuit is to increase the selectivity of receivers with ferrite antennas. The circuit...
This solid-state relay circuit (SSR) or shield is from a 1995 Electronics Now. With it we can...
We show a channel of a simple preamplifier for ceramic capsules. This circuit is based on a very...
