its should be (8.457*10^-4)^2 in Denominator

[kanchigupta]

Hello sir, for getting x(t) max, you will have to differentiate the expression x(t) and find t for Xmax.

[ahmeddesigner]

sir, in the last question : the point number 2 so BW will be 1MHz, so Fs will change also and by assuming bit rate is constant so no of bits will change to can calculate SNR

[avarun]

Sir in your earlier video, you presented an example where variable W was maximum frequency and Bandwidth = 2W. In this video and in last example, you used variable W to indicate Band Width. Could you please tell me how?

[anveshreddy]

Sir kindly change the answer for maximum value... Ur assumption is correct sir but both sine and cosine values never be 1 at the same time
Even though they are in phase max value is at 45 degrees ie root 2

[gamingaccountseller]

sir for sine signal can we directly use 1.8 + 6n

[JemmyFM]

not 4.166 its 25 for the last question

[زهراءفايقتوفيق]

Please sir I have questions if you don't mind when we calculate x max it become 6 why you multiply the second term by (-1) evenrthough it max I thought that max part supposed to be multiply by(1) because sin range of max part Is (1) I just didn't get this part could sir please explain it to me I will be grateful yours videos is marvellous thank sir

[payelbanerjee]

Sir, what is 1.8+6n db ??? Is not it quantization SNR

[rdabrar]

I can hear some background noise in your videos. Please try to remove them in future videos.
