The emitter resistors didn't seem to do anything so you could omit them. If it doesn't do anything, measure the voltage on one of the bases and adjust the base resistor or the supply voltage so that the base voltage is about 0.7 volts. If it goes part way across the screen and then stops, you should wait to see what it is going to do. The output really slows down for oscillating circuits like this, so you may have to wait a while to get a display. I found 560 ohms worked for a 300 volt supply, but this will vary with the exact transistor you are using.
Multisim 12 not responding windows#
Must've been something that didn't get copied over during the cloning of my HDD to SSD, or something was corrupt and the repair of Windows didn't catch it. So, I went ahead and made a backup of my SSD, then completely wiped it and reinstalled Windows. To get higher voltage operation, you can put resistors from base to ground for each transistor. Re: Multisim 12 Student/Education Edition Won't Start. Start off with a horizontal scale of about 1 second so you can see if it oscillates at all. There is also a delay before it gives any output, so you could miss this if you put it on a sweep of a few microseconds. It oscillates if I change the power supply to 2 volts and the capacitors to 50 nF. I don't have Multisim, so I tried this with LTSpice. The one that worked or the one that failed at many different input settings? So basically which scenario should I believe now ?
Multisim 12 not responding generator#
The thing is that I made the generator and it worked all ok.Then I did some analysis and all was ok, then I thought hey I should try it on a copy file just to see if all is ok and then well you see it nothing is ok.:DĪlso I changed the base resistor values from the npn totally open to totally closed that would be some 100k in range or more and it just gave me a weird triangle like distortion with a varying frequency or something like that or it just gave me a straight line dc.īut before in that same range I adjusted my needed resistance with potentiometers and set in a resistor after that and all worked. Well basically I need a square wave from the multivibrator to switch some mosfets, ofcourse there will be other circuitry but this is the main one.
Multisim 12 not responding code#
I don't have MultiSim 13 so I can not simulate the circuits that you make with MS 13.Well yes I understand what you mean but basically spice just like any computer program works like the binary code and if i put in some certain value then some certain outcome must be there and changing these numbers also the outcomes should change. I have an old MultiSim 2001 that I got with my textbook. Using formulas above you can calculate V across Rload and/or I through Rload. Where is Pout? It seems to me to be the power at the Rload. Since the signal is from 300 Hz to 7 kHz, we could be talking about some kind of audio system, so the Rload/strain/workload could be an audio speaker that is 12 Ohm. The parameters given tell us that the input resistance (Rin, the resistance that the input voltage source see) is 2 kOhm. But they do not tell us what parts make the circuit. They tell us how the circuit is supposed to perform. Repeat until you reach 7 kHz.Īll the other numbers look to me to be design parameters. Increase frequency, run simulation, get oscilloscope graph. Set frequency to 300 Hz, run the simulation, get oscilloscope graph. Again, since you need to simulate and observe the effect of frequency, you will have to manually change the frequency. Put it into schematic, double click on it, a window opens up, select the type of the wave you want (sinusoidal, triangular, square), frequency, amplitude. to 7 kHz)?Īnother way to do it is to select Function Generator. Did you instructor tell you the frequency steps? Are you supposed to do it every 100 Hz (300 Hz, 400, 500, 600, 700. Then change the 300 Hz to next frequency. You can do what I did in my example of your circuit, in MultiSim select AC voltage source and put it into schematic, double click on it and a window opens up, in that window select 20 mV amplitude and 300 Hz frequency, do the simulation, save the oscilloscope graph. ASSUMING that Uin has amplitude of 20 mV (20+20=40 mV Peak-to-Peak). Click to expand.Uin and F make sense as inputs.
