Questions tagged [pulse]
A pulse in signal processing is a rapid, transient change in the amplitude of a signal from a baseline value to a higher or lower value, followed by a rapid return to the baseline value. There are many examples of a pulse function including: Step/rectangular pulse, impulse/dirac pulse, triangular pulse, sawtooth pulse, sinc pulse, Gaussian pulse, etc.

Collector and Emitter of BJT are always shorted [closed]
I am testing a circuit and i have an npn BJT in that.
I am supplying a 5V pulsed source to the base of the BJT at node C. And a constant -5V input at node A. Note the frequency must be 10KHz with 10% ...

Level shift a 0-20 V pulse to +,-10 V without deteriorating the rise time
I need a fast +,-10 V pulse. I thought I could trigger the base of a switching transistor with my fast rise time digital I/O and get a 0-20 V at the collector and then shift the DC to 0 volt and have ...
