Are the properties of a DC Pulsing Circuit the same as an AC Circuit given the same frequencies? This is the first of your video's I have seen... and as an intermediate knowledge learner its the best technical quality video I have seen by topic. Love it, thankyou.
In the video on Input Offset Voltage you assumed no Input Bias Current, in this video you assume no Input Offset Voltage. How convenient ... 😄 In real life they are both present and influence the output voltage. A video that would analyze them both would be cool! Great job anyway!
Is it possible to reverse drain and source in a FET ? I mean can we connect +ve voltage to the source and -ve voltage to the drain of a n-channel FET and expect it to work as normal n-channel FET?
Why are other characteristics of the transistor not taken into account in the calculation, such as the volumetric resistance of the base and collector?
Would you be able to confirm the accuracy of calculations on a specific example of a transistor in some circuit modeling program, for example in a Multisim?
I really appreciate your videos and that you are explaining step by step in this playlist. I would love to see you make videos on other classes as well like class B and AB
*WHY HIGHER LOAD RESITANCE SPEAKERS CONSUME MORE POWER*---I have seen speakers with higher impedance like subwoofers are of high resistance value 8 ohms but normal speakers are of 4 ohms. But then why subwoofers are of higher wattage than 4 ohms speakers? When lower resistance load is connected to a power source, more current should pass.
An example of thermal noise reduction: many oscilloscopes have a 20 MHz low pass filter to reduce noise that is introduced by the instrument. This is helpful for measuring small signals that have low frequencies.
Thank you soooo much for these videos about noise. I have always been confused about noise and how it works and I simply didn't find any sources to explain it well. Watching your videos, I understood it immediately and can now go forward to create much more precise models for my circuits. Thank you Prof. Danner!
Really enjoy the videos but feel it would be nice to drill down more on the exact calculations for the capacitors. I realize that staying above certain values guarantees the signal integrity but if looking at everything, I think it would be helpful to include them. Thanks and great job on going through multiple examples. 73...
@12:00 shouldn't that be 1.2k // 1M ? Since the collector is tied at one of its ends to a DC source, it's therefore connected between the collector and an AC ground making it in parallel with the one megohm load, right?
Hello, hopefully you can help, this is a rather difficult answer to discover for me due to the close relationship to a much more popular question. Your video covers the popular question, my question is what rules do you abide by when you DON'T use a buffer, for a little bit(Obviously not "at all", what rules should one follow extending the filter circuitry a little further prior to inserting a buffer?
I do electronics as a hobby and filters where things i found quite complicated and stayed away from learning in depth. After finding your channel and playlists i am finally understanding.
Excellent explanation but is it just me or is there something about the way he says vOLtage. It’s like he is being shocked with some voltage when he says the o in vOLtage. Like stewy and the way he said cool Whip
In few materials I have read, the single, thin wire above the 3-phase HV wires is just for lightning protection. It either go directly to the local ground (pole ground), or through a resistor to go to the ground. In those articles, they never said it serves as neutral wire as well.
Awesome Aaron, it's great to do the maths and also some picking ballpark numbers and fitting them and checking that the results do what we want....cheers.
Kind of suddenly struck me that the apparent resistance of a capacitor decreases with increasing frequency, so, thinking in the time domain, as we switch the capacitor more often, its "resistance" decreases, and more of the signal is shunted to the common/ground... funny that I hadn't thought of a capacitor as a "frequency-dependent resistor", when I've actually designed a current-measurement circuit that uses a switching capacitor to make a current-nulling node.
This was a fabulous presentation. I really appreciate that you dove deep when necessary but kept us aware of the high level requirements and constraints. This would've is been great 25 years ago during my degree! Thank you!
Dear Aaron, thank you so much for these series. I wish I had a supervisor like you during my masters degree. It was brief but had everything one needs to know to start designing and simulating. well done. Which reference book would u suggest for Integrated filters and which one for discrete filters on PCB? I want to designing a filter to maximize 1th harmonic and suppresses 3rd harmonic heavily for a cross couple oscillator or a filter that has same passband response for 1th and 3rd harmonic and suppresses rest just like class F oscillators /PAs. sorry for asking lots of questions
