This circuit is indicated for the analysis of pulses in TTL circuits. The circuit is from a documentation from the 70s and must be powered with a 5V voltage.
This circuit allows the "recovery" of weak signals recorded on tape that correspond to programs. The...
This circuit uses two JFET such as the BF244 or BF245 and has an excellent gain with small...
