Hi guys,
i am new here but i really like this place. I am currently studying electrical engineering at the university so i am still learning. I have a problem figuring out a circuit and i wonder if anyone could help me. The circuit is this https://www.4qdtec.com/mvbz/smv1.gif and some info about it can be found here 4QD-TEC: Multivibrators and Relaxation Oscillator Circuits . It is a series multivibrator that produces sawtooth signals. However, i can't get it to work right. I connect a dc supply between the two horizontal lines on the top and bottom of the circuit (+ goes to the top line) as well as a ground to the bottom line. I take the output from the collector of the npn transistor (the upper one). Can you help me understand how this circuit works? Also, can you help me choose the transistors and diode to make it work? Thanks a lot guys
