[visweswararaovk]

Most of us come to know the beauty of any subject, only when taught by a legend like you, sir.

[Rafi-hj]

Such selfless catering of knowledge! I wish your good health and long life so that you can keep spreading the light longer.

[tanmoydutta]

Such a clean explanation of the low-pass filter, and smoothening capacitance....Really appreciate the efforts of this professor in explaining the topics

[observer]

I was today years old when I realized I could scroll down while the video was full screen.

[rupamsinharoy]

Now i know where did my college professor learnt these concepts from 😍😍😍😍😍
These lectures are treasure for the humankind. Love you prof. Thank you so much.

[gyaneshchaubey]

you are best electronics teacher i have ever seen, thank you very much for ur great effort sir....

40:39 Vout not equal 2*V0 - VD, on (but corrected to Vin - VD, on = Vo - VD, on at 40:55)

[mateen]

40:33 *Voltage across capacitor is V0-VDon

[WenyangQiao]

is there someone can explain me that in the half-wave rectifier case, i dont konw why the diode turn off when the output voltage of capacitor reach the peak，why dose it stay constant ?. just from the Mathematical equations(V_o=V_in-V_D), V_o should decrease with V_in decreasing

[thanoskaraiskos]

Last equation does not make sense for me.
Ripple Amplitude = (V0 - VD, on) / (R1 * C1 * fin).
If we have a small device, the R1 is going to be small so the ripple is going to be big. That does not make sense for me.

Awesome lecture razavi sir
Thanks a lot

A very silly mistake over the lecture after 25:00
Output voltage = Vo - Vd, on ( wrong)
Correct is = Vin - Vd, on

[adeddy]

21:42 the rate of change of capacitor voltage should be lower than the slope of input voltage i.e the capacitor will charge slowly and than the input voltage change
Plzz correct me if i am wrong

[saikrishnagarlapati]

Where did he mention about a low pass filter before?please Let me know...

[nickbohr]

I didn't get the point when he excluded the option of output voltage going up 18:37

[dr.asadnemer]

hi doctor razavi
where we can find the note that u save it in smartboard in this course???
please help us

[tanmoydutta]

Sir, why can't we plot the transfer (I/O) characteristics for the half-rectifier diode with smoothening capacitor at 33:14 ? Since, by applying KVL, V(out) = 0, for V(in) <= V(D, on) and V(out) = V(in) - V(D, on) for V(in)>V(D, shouldn't it be a straight line on the input axis till V(D, on) and then an inclined line with slope = 1 thereafter?

[sakshisingh]

so basically to decrese ripple we need to increase capacitance. can anyone tell me what if we put a buffer in between cap and load then i guess load won't affect the voltage across cap so i guess there won't be any discharging?

[chassenk]

Better tha the useless Profs at UTEP, way better
