I' ve watched previous videos, but I didn' t find any reference to the arguments treated in the 2nd part of this video (ratio, LCM, ...). Are they treated in another playlist?
Doubt: In the 2nd example. where we have a composite signal. Does the order matters? For example: x1(t)= sint + cost and x2(t) =cost+sint , are both x1(1) and x(2) signals different?
dear sir there are may major problems that what your teaching here, its available all in book but when that comes to the exam problems then actually it became a lot difficult. Please try to post problems generally based in exams . thank you
Sir, could you please tell me the answer in this question sir Find whether the signal f(t)=10sin12(πt)+2u(t) is periodic or not?if periodic what its fundamental period could please tell the in this problem answer sir
Sir ! Please suggest me some good reference books for my academic purpose for signals and systems, and linear system analysis I'm a student of electronics and communication Engineering !
On working sin(4πt)*sin(4πt) you will be getting time period as 0.5. 0.5 is also a time period but not fundamental time period(fundamental time period as in video is 0.25 and 0.5=2x0.25). While solving we must try to reduce the given term as nonsquare (as in this case), if we are not able to do so we can then follow the conventional method.
Sir plz provide solutions for this discrete time system input x[n] and output y[n] .y [n] =x[ n] x[n-2] is the system memoryless( 2)determine output of system when input is A∆{n} where a is real no (3) is the system is invertible
Can you write the whole problem please? What you want from x(t) = 2cos(2t+pi/5) If you want to calculate fundemental period of this signal it is easy to see actually fundemental period of this signal is 2pi/2 which means 1
And also x(t) =e(3+j)t for this signal if you can not see directly you can use euler's formula and change the signal from exp to sin and cos than it will be easier to see
