5–56 UsingMultisim, create the following waveforms and state if eachwaveformiscausalornon-causal,periodicornon-periodic:

(a) A step voltage switching from 0 to 5 V at t = 100 ms.

(b) A triangular wave that has amplitude of 75 V and a period of 10 ms.

(c) A cosine with amplitude of 100 V, radian frequency of 2000π rad=s, and a phase shift of −45.

(d) A positive sawtooth wave with amplitude of 5V and a period of 100 ms.

(e) A charging exponential starting at −10 V and growing to

+ 5 V with a TC of 1 s.
