Amplitude of full wave rectifier sine wave clipped

[bila ljaved]

Please all answer my following question


A Full wave rectifier sine wave is clipped such that the effective value is 0.5 ym. the amplitude at which the wave form is clipped will be?


Thank you all in advance

Hi Bils,
Could u pls provide entire circuit ?

That is a meaningless question. What is a "full wave rectifier sine wave" supposed to be? Presumably it means the output of a full wave rectifier that was fed with a sine wave.

Also, what units are 'ym' ? It sounds like a badly worded question about the difference between RMS and instantaneous values.

"ym" is Yummy!:grin:
I say it every time I see a pretty young lady. ymmmm

Dear Shunmuga Sundaram,

thank you for your reply.
i saw this objective type question in a book, but there was no ckt mentioned in that book.
can you please still answer this question?

Dear Brian,

ym probably seems me like it is the peak voltage like Vm is usually mentioned in the book.
can you answer it now?

 

[kam1787]

if Ym is Vpeak then surely the answer is 0.5V

More likely Ym is RMS or Average, but who can say

Eveyone is right, the question is ambiguous.... but I like Audioguru's explanation best :-D

It seems me like we shouldn't waste our time if even the OP doesn't know for sure what the questions means.

Secondly, yes I know how the problem can be solved if ym means sine peak. Consider the definition of effective value and review your mathematics handbook for integral of sin²(). I presume you already sketched the waveform.

if Ym is Vpeak then surely the answer is 0.5V

I agree there's a solution for all suggested meanings of ym, but the answer will be > 0.5 in all three cases, I think.

The waveform will be comprised of a clipped flat top and a sine part. RMS calculation of cut sine waveforms has been discussed in a recent thread. https://www.edaboard.com/threads/282845/

Yes FvM, the answer is 0.581ym but how ?
