Question
Q3. A current signal has the form (i) (ii) 1 (t)= Ke-10t cos (50 t-). Amps Sketch a graph of this voltage signal with labelled axes for t = -0.04 to 0.04 seconds State whether this function is an even, odd or unsymmetrical function. (iii) State the limiting value of the function as t approaches infinity and minus infin
