    Homework: Sawtooth generator using a thyristor

    k, no problem, I believe I will try out a few circuits given in class and hope to get a scope image that way. Thank you.

    Homework: Sawtooth generator using a thyristor

    Yes, I have the exact output but unfortunately our teachers demand Multisim circuits. Therefor I can not use your circuit as is. I am glad to see a perfect sawtooth and I'll try to understand your circuit furthermore so I can rebuild it. If anyone else can help me out with the multisim...

    Homework: Sawtooth generator using a thyristor

    Any chance you can port it to multisim?, I'm not quiet familiar with Proteus. I'm trying this myself but I'm failing once again. EDIT: I noticed your input signal to be a pulse of 150V not exactly DC ? :s I don't have a problem with that since it hasn't been asked but how to do this in multisim?

    Homework: Sawtooth generator using a thyristor

    Yes, I did find that video earlier BUT I can't seem to get a sawtooth scope image in multisim! :s I'm using a tektronix oscilloscope but even at auto-set the scope-image is a flat line.... What am I doing wrong? Your explenations and circuits are well apreciated! but I can't seem to set my...

    Homework: Sawtooth generator using a thyristor

    Hi, Can't seem to find a sawtooth generator with a thyristor that is working as it should. Anyone who can exactly accomplish this given task? Design a sawtoothgenerator including a thyristor. Explain how it works with the components used and calculate the amplitude and frequency of the...

    Thyristor 230V Backup circuit

    Hi guys. Again some homework I can't seem to get my head around. Design a circuit, including a thyristor, where a lamp of 6V fead by the electrical grid (via a transfo). The lamp should be kept burning when the grid power is removed. As backup, use a 9V battery. My circuit is this: When I...

    [SOLVED] Amplifier (+frequency response) ??? homework

    Many thanks to everyone for all the help. Some came a bit late for the task at hand but I learned more than I could wish for! @E-design: I might need your help in the near future ;) if that's ok. @countmybones: It looks very very informative, I'll take a closer look soon. Thanks again all!

    [SOLVED] Amplifier (+frequency response) ??? homework

    I'm sorry, I'm not englishly rooted :P so didn't read it the right way. Thanks for your help! I got different but right values I think. greetings

    [SOLVED] Amplifier (+frequency response) ??? homework

    @chuckey: What's your value for C1? @E-design: you replace a capacitor with a resistor?

    [SOLVED] Amplifier (+frequency response) ??? homework

    Hi, We have a homework task to create an amp that will amplify 200mV to 2V over a load of 10kOhms. I'm using this forum as a very last resort to get some straightforward help in the form of a full circuit. The function generator is supposed to operate at 1kHz (200mV). That's about all I know...
