Ok. Im working through a tutorial, this is not work any marks apart from person education and satisfaction. PS solutions are given. i will attach files as proof so people don't think i hunting for an answer for an assignment. Im struggling to find a comprehensive video on you tube or article to read giving a good explanation. so im here.
My question is regarding the last 2 questions ( last page), where it asks to draw the Vo waveform from the circuit. PS it isnt stated in the question but during the tutorial video the lecturer states that on the last question (the one with the capacitor) the RC time constant it to large relative to the waveform frequency for it to have an effect on Vo waveform.
So i understand that with diodes Va>=Vk for the diode to be on ( using idea diode models in analysis) and if this is not a true statement then the diode is off. And with the AC and DC involved in the circuits you analyses the DC first (superposition) then analyses the AC waveform (pos, neg cycles or important points of voltage on the waveform) taking into account any effect that the DC voltage has on the Vk or Va of the diode. but im having trouble putting this understanding into systematic math to give answers of with i can simply drawn a rough graph relative to my math awnser.
I have watched the lecture explain the solution although it is not clear, mabye to much assumed knowledge and shortcuts taken.
Cheers
