Electrical Characteristics of Audio Amplifiers
We learn the .FOUR command and how to find the total harmonic distortion, as well as how to calculate the power supply rejection ration and the common mode rejection ratio.

Love your tutorials. Thank you for the great work!
Thank you very much!!!
Thanks for the explanation with the stepped parameter
Clear, concise and instructive. Nice video Mary. Thank you.
Thank you for this tutorial. Much appreciated.
Brilliantly explained, from creating the sub-circuit in schematics (and why we need to save the sub-circuit node voltages and currents for later probing through the symbol to be successful) to making of the symbol. Thank you so much.
Oh dear god what is with the background squeal?
That was very clear. Thank you.
Thanks so much for sharing these LTSpice intro videos, Mary. Very clear and very helpful.
Thank you, Mary
I hope you will put in the description box the files you used
thanks. :)
Now simulating an RC-Filter for the beep in the video.
where are the three noises?
This is impressive, but how was it done? Without providing code or hardware designs, posting something like this seems pointless.
Omg you are a genius
Thanks for the tutorial. Looking forward to seeing more videos
One very minor request: Please label nodes, paths, components, etc. and refer by name in your commentary. If you simply point and say "this one" or "that one" it can be tough to follow at times. Thanks!
really good stuff! Thank you for this video, I am new to LT spice and I need to be able to simulate opamps in lt spice for my grad school thesis.
Your video really helped me the most in getting started. thumbs up!
Why did you stop uploading videos?
Reeeeeee
wtf is this noise. It destroys the whole video.
Very clear and easy to follow. Excellent tutorial.
Clear and helpful, thank you!
Warning : Watching this video series with audio can be harmful for your ears
Brilliant. Thank you very much!
Great. No more background squeal!
Another good, just-right tutorial. Everyone starting with LTSpice should start with these!
These videos are really good, but I expect many viewers to quit almost immediately because of the squeal. What a shame! (I found an easy fix. See end of my comment.) Nice and simple video. For newbies like me, I recommend unchecking Control Panel / Drafting System / "Automatically scroll the view". The squeal is bad but turning the volume down helped. I recommend running your audio through a notch-filter to remove it. These videos are worth the effort to remove the squeal. The squeal can easily be removed with the free Audacity program. Downloaded a portion of the audio from the beginning of the video. Be sure to start audio capture a couple of seconds before she begins speaking. Under Audacity/Effects select Noise Reduction. Select the part of the recorded audio before she speaks to allow Audacity to identify the type of noise and suggest a correction. The squeal can be completely removed with minimal effect on the speech.
I followed this to the letter and still got "unknown component" warning from Ltspice????
can i have this code...pls say
interesting. Normally i would just change the value each time.
How ironic title
noice
This video was great but can you please not just say "with a little bit of fanangling" and show what you actually did....? To people who are trying to mimic and follow it along, it does not help when you just randomly decide to skip a crucial step.....
Hi, I shouldn't have mentioned the fanagling - I was referring to what is needed to be done to import third party spice models. That is a separate tutorial. Sorry for the confusion.
Block 4khz in eq to save migraine.
Your sound is very nice..
Thanks alot for all of these video tutorials. I found it alot better to watch Video Eight before watching this video to be able to follow along and do the same thing. The power source is the same as in the previous videos except with a 1V AC signal on top of the 5V DC signal. The speed in which you go trough everything is great, some people dumb it down to much making it to slow, but since it is a video its easy to go back and see it again. Keep up the good work, I look forward to see any more videos you might make.
Love this! I tried a bunch of other ways but this worked best for me! thanks!!
Please use a better microphone next time. The poor audio quality and the ringing throughout the video makes this otherwise useful video hard to watch.
I am in the process of re-recording these with professional gear for a new channel. Apologies for the sound quality.
@@marywest2235 That's great. Thanks. Would you be able to link to this new channel once it's up please?
I think that was the clearest explanation of gain bandwidth product I've come across.
Great tutorial!
the audio on this video needs a low pass filter
mV=millivolts, MV=megavolts.. that's -10,000,000 volts right there

EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
Could you please re-record the audio for this video? That noise is really distracting
good
Nice tutorial but the background noise disturbance.
