This is an excellent tutorial, Professor. Thank you. Yes, the concepts were clearly explained. If I may make a humble suggestion... The vocal audio is quite distorted and difficult to understand. I imagine that you are very familiar with audio circuits, but here are some things to try, before spending money on new equipment... The audio chain is usually = Microphone to Preamp to Main Amplifier to Speaker, or other form of output. You need to make sure that no element of the chain is over-driving the next element. Meaning the gain of the proceeding element is not greater than the gain of the next element. This is accomplished with the equipment volume/gain settings. Even your voice can over-drive the microphone, so do not place the microphone closer than 2"/50mm to your mouth. Additionally, your fine, deep voice naturally has a lot of bass tones. When the equipment processes those tones, the vocal clarity can become "muddy." This is because each piece of equipment has greater efficiency in some tone areas than in others. This is corrected with the tone controls. The better method is to use a graphic equalizer and to reduce the vocal tone frequency in the 250Hz region. I hope this helps and it is offered with much appreciation for your efforts to teach us.
hi, good explanation thank u, i have a smps 12v 30A , without load smps is provding 12v out., after i connect 12v 100w halogan bulb to output ,the right side transistor burns mje13009k, why is that? pls help.
at this moment no internet sir, only youtube can watch. i will upload the video, sir why led 50w is working and halogen bulb not support.? some smps supporting halogen bulb.
