Chuck asked about radio receiver simulations: "1.How do I add a antenna. Or can I use a 27Mhz voltage source." SPICE doesn't do antennas. Yes, you can use a signal source, connected to the appropriate

Hopefully this is what you need? Sent a message with a question seperatly then saw this email

Actually a BUNCH of questions. LOL 1.How do I add a antenna. Or can I use a 27Mhz voltage source. Need to modulate it with 1K sig. How do I modulate the 27Mhz. Was able to model a sine wave source at

I am sorry if I sound ignorant or misled by my own lack of understanding the problem at hand but a little while ago In this forum I derived some equations for simulating an electrostatic loudspeaker

Hello, I am sure the MODULATE block works as a FM-modulator as expected. You can check this, if you do simulation followed by a FFT. You will get the frequency spectrum as calculated by math. Best

PhB, Thanks for this helpful suggestion. I am amazed that I was able to find your correct answer while searching for completely unrelated information!

Helmut, Would you, please, reveal the math performed by the MODULATE block on the "FM" input? Does it add the integral of the "FM" input voltage to 2*pi*fspace*time in the same way that one would

Another important point is the "twisted pair" requirement. The question seems to have an implied EMI (Electro-Magnetic Interference flavor.? On that assumption, I mention that not only is the

Using the BI worked. thanx!

think of it this way - the loud speaker is like a solenoid https://en.wikipedia.org/wiki/Solenoid#Electromechanical_solenoid or a variac

Add to your schematic a B type current source whose current is the sum of the three line currents. Connect a resistive load to it to prevent its voltage becoming infinite. Then take the FFT of the B

I have a 3 phase twisted set wire radiating noise. I've constructed what I believe if a sufficient filter to knock the noise down to acceptable levels. What I need to do is take the FFT of the average

Hi Andy, Thank you very much for your very quick reply and taking your time to explain details. I will continue with this query after my personal errand. Best regards, Eric LTspice@...>

Thanks for taking the time to explain Andy. Joe McCarron

I'm having this same issue. Reproduced on my Macbook Pro running Sierra (10.12.6), and my iMac running El Capitan (10.11.6). It is not a mouse issue - it's a graphics-layer issue. Whatever canvas

Hello Andy, I found a part MOC308x and uploaded into my library. I couldn't make it work. Maybe I have not done it correctly. But I also found a circuit containing the same part that has been "solved"
