Simulating a Logarithmic converter

[ztjust]

Hello, I'm having issues creating and simulating a logarithmic converter.  I'm supposed to use a LM741 op-amp, and I'm supposed to use a potentiometer to increase the voltage from 0.25 to 5.00 volts in increments 0.25 volts, or a DC variable supply.  I need to then measure Vout using a Multimeter or something.  I've been trying for a while, just hope someone could help me out.

Hi,

I would say using a DC supply and run a quick DC sweep would be the simplest approach to finish your task. To do so, go to Simulation->Analyses->DC sweep. There's currently no easy solution to vary the potentiometer setting on the fly. Hope this helps.
