What is the sin square standard formula in 4th question

[@padmavatisreekanth191]

Sin2@=1+sin2@/2

Just dropped by to encourage you to continue doing this. Your explanation is simply amazing. Thank you.

Can we directly find LCM of 10 and 9 is 90 .... So period should be 90 sec right????

[@_preet__20__]

1. T=0.5 sec 2. T= 100 samples/sec 3. T= 7 samples/sec 4. T=0.25 sec 5. non- periodic

[@unwanaibanga4297]

Hello Sir, thank you so much for your video. Please I would like to kindly draw your attention to the last solution. The LCM of 9 and 10 should be 90 not 1800. Using your method, after simplification lambda 1=9 and T1 = 10 so that the period T = 9 x 10 = 90sec. Thank you

[@akashsinghmbbs8246]

Bro lcm 180 and 200 ka lena hai na ki 9 and 10 ka

Hello, sir. May I know if what book do you use? I hope you'll able to see this comment. Thank you for doing this kind of tutorial

[@okokicici]

sir your videos helped me a alot systematic way of teaching sir pls upload more videos on this signal n systems it helps a lot

@@techaj6987 sir how to solve sin^3(2t)

[@techaj6987]

We can find signal is periodic or non periodic if its in sin / cos form. If its sin^2/ sin^3 convert it into normal sin / cos form using standard formulas for sin^2(t) or sin^3(t)

[@techaj6987]

sin3x = (3sinx - sin 3x)/4

[@okokicici]

@@techaj6987 yeah I solved using same method but I'm getting wrong answer

how do we know if a signal is DT signal or CT signal?

[@Ghumnarecord]

Sir in the last for home work is non periodic na?

How to do if x[n] is ratio of two sine signals i.e., x[n] = sin(200n pi)/ cos(123n pi)?

[@tsehayenegash8394]

You have a deep knowledge. I have 15 years temperature data. I want to find the phase shift and the amplitude of these temperature data. my guide equation is X(t)= ao + sum(i=1 to 2)Ai(cos2πi/pi(t-fi)), where ao is the average of the givin temperature, pi is the period which is annual oscillation and semiannual oscillation, t is time of the month, Ai is the amplitude of annual and semiannual oscillation, fi is the phase of annual and semiannual oscillation, 2πi=12 month/i. so how can I calculate Ai and Fi at a given temperature data?

Hello sir, x(n)=cos(pi/2 n)+sin(pi/8 n) can you please help me solve this example?

[@techaj6987]

Here signal is DT & combination of 2 signals [ x1(n) = cos(pi/2 n) & x2(n)= sin(pi/8n) ]. So for both signals find period & take lcm as mention in some examples of video

Why, as in the second example, the period is just the denominator of the frequency? Sorry for the question and thanks a lot for the video

[@styluxmusic]

because frequency = 1/T where T is the fundamental time period, so yeah it just comes from the formula
