Day 1 :
SS:U1:
Q1. Is the signal
x(t) = 2sin(2/3)t + 3cos(2π/5)t periodic ? If so, what is it's period.
Q2. Sketch the even and odd components of x(t) = e^-tu(t)
Q3. Is x(t) = cos2πfot a power signal ?
Q4. If x(t) = A for 0<t<T. Plot x(2t) and x(t/2). What is this operation called.
Q5. What do you understand by the term BIBO stability ? Explain mathematically.
Q6. Write the mathematical formulae for finding the : Fourier transform, Laplace transform for a given function f(t). What is w and s ? How are they related ?
