Open one plot pane, say the Y1 plot. Right-click on the X-axis and look at 'Quantity plotted' in the pane that opens. If it gives you a choice, pick Y2. It may not give you a choice. -- This email has

Hello Andy,I have two Y axes plots depending on the same X axes. I want to create a plot of Y1 vs Y2. Is it possible in LTspice? Thanks.

That depends.? Be more specific. Andy

Thanks Tony and Andy.? I'll try out GFARAD, sounds like it's the 'right' approach here.? I should study the wiki documentation for undocumented bits more closely.? Tomorrow I might try it on my

Hello, nasickly I have Y1 vs X? and Y2 vs X ,Is there a wat to combine them so I'll get a Y1 vs Y2 plot? Thanks.

Dear Dennis, A very good day to you. Once again thank you so very much for answering all my questions. I am grateful to you, teacher. I apologise to you for replying with a delay. I will make use of

Having posted a schematic (.asc) would probably have helped clearing the issue.

I think that is not quite true, but it is one of those "surprises" that you may not have realized was there. The LTwiki ( here (

Thank you, but that crazy filter is not my design.

The "annotate steps" is in the "notes and annotations" menu you get after right clicking in the results menu after a successful step'd simulation. Cheers Ian

Hello John, The land of dB can be confusing at first.? When dB was invented, it was a way to keep track of power, as in watts.? Each +10dB was 10 times as much power. Recall that power, P = V^2 /

This is very OT, but dBm is very widely applied to 50 ohm circuits in the RF field. -- This email has been checked for viruses by AVG antivirus software. www.avg.com

No, it's not. dBm applies only to 600 ohm circuits. If you want independant on load, you must use dBu (or dBV).

To be very precise, 0.775 V is approximately *equivalent to* 1mW in 600 ohms, which is sqrt(600x0.001) = 0.774596... That is the explanation of the voltage value. -- Best wishes John Woodgate RAYLEIGH

Bruce: https://en.wikipedia.org/wiki/DBm In audio and telephony, dBm is typically referenced relative to the 600-ohm impedance[4] commonly used in telephone voice networks, while in radio-frequency

0 dBm is 1mW independent of the load resistance. Bruce

Actually, 1Vac is meaningless. Could be 1V rms, 1V peak or 1V peak-to-peak. The dB value is always referred to the input voltage, whatever the unit. In order to have the results expressed in dBuV, the
