The circuit in the figure uses two operational amplifiers: an LM101A and an LM102. Diodes admit equivalents and resistors do not have to be accurate. The power supply must be symmetrical.
A rectangular signal applied to the input of this circuit becomes a negative pulse, which...
This circuit was found in a 1980 publication, but it can be assembled using a BD135 for Q1 or even...
This circuit, suggested by Sylvania in a 1956 publication, serves as an experimental stage for a...
