Hello I would like to ask if the connection for the oscilloscope to see the sawtooth wave is from the positive terminal is emitter (middle line) and negative terminal is the ground? thank you. we can't get the sawtooth for a particular circuit >

[@LewisLoflin]

Sawtooth is on the emitter.

@@LewisLoflin is it ok if I mail our circuit from multisim? we can't get the spike for the Vb1 and Vb2 😢😢

@@tracesofthesunjingab Got your email and I'll have to build the actual circuits. I never use sim software it doesn't work much of the time.

@@LewisLoflin thank you sm, it's a lab activity and will be passed later. Now for sure we are wuite confident that there's something wrong in the circuit as we cant get to see the pulse/spike. Tysm 💙
