Using Multisim, create the following waveforms and state if each waveform is causal or noncausal, periodic or nonperiodic:
(a) A step voltage switching from 0 to \(5 \mathrm{~V}\) at \(t=100 \mathrm{~ms}\).
(b) A triangular wave that has amplitude of \(75 \mathrm{~V}\) and a period of \(10 \mathrm{~ms}\).
(c) A cosine with amplitude of \(100 \mathrm{~V}\), radian frequency of \(2000 \pi \mathrm{rad} / \mathrm{s}\), and a phase shift of \(-45^{\circ}\).
(d) A positive sawtooth wave with amplitude of \(5 \mathrm{~V}\) and a period of \(100 \mathrm{~ms}\).
(e) A charging exponential starting at \(-10 \mathrm{~V}\) and growing to \(+5 \mathrm{~V}\) with a \(T_{\mathrm{C}}\) of \(1 \mathrm{~s}\).
