    How to calculate periodic jitter from a spectrum of a signal

    Hi Westrace: Jitter is integrated phase noise, so if you are able to capture a phase noise plot of the clock in terms of dBc/Hz, then you can numerically integrate the phase noise to get jitter. I've attached a spreadsheet I grabbed from RF Globalnet as a starting point...

    Multiple Equation Solver in Excel?

    electricpete: This is pretty interesting. It looks like it does most of what I'm looking for. I'll have to try putting in some other equations to see how easy it is to adapt to other uses. Thanks Dave

    Multiple Equation Solver in Excel?

    Hi All: electricpete: You've described the situation pretty correctly. This is an example of a pretty generic engineering problem, where you have a set of equations that describe a system, and you know some of the parameters, and want to calculate what you don't know. The example I came up with...

    Multiple Equation Solver in Excel?

    I'm trying to convert between dBm, (dB relative to milliwatts), dBW(dB relative to 1 Watt), Watts, milliWatts, and Voltage across 50 Ohms. I'd like to be able to enter one of those input numbers and have Excel calculate the rest. I do have R set as a constant. The equations are all simple, but...

    Multiple Equation Solver in Excel?

    Hi All: yakpol had the closest description of what I'm trying to accomplish, but it didn't work very well. You were right that the initial values need to be pretty close, and that's sort of a deal breaker for me. I guess I'll stick with my Calculator for that. I've attached my spreadsheet if...

    Multiple Equation Solver in Excel?

    Hi: I'm trying to set up an Excel worksheet that solves multiple equations for unknowns. For example I'd like to have equations for power and voltage drop across a resistor, and have Excel solve for Voltage, resistance and current, given enough variables input. I can do this on my HP49, using...
