This circuit was found in documentation from the 90s, being indicated for the deflection of cathode ray tubes. It consists of a DC voltage amplifier and operates at frequencies up to 1 kHz.
This follower, found in a 1982 documentation, has only one amplification step, but it helps in the...
Originally suggested by Electronic Design in a 1965 documentation for use with oscilloscopes, this probe has...
This circuit uses two LEDs to indicate the state of a battery, the voltages at which they...
