[complex numbers application: transfer functions] you will deal with many "transfer functions" in your career as an electrical and computer engineer. the transfer function tells how the input and output are related for a given system. here is an example from the first midterm in ece 310, with some extra scaffolding for you, of course. suppose that i have an input signal of the form x(t) = a1e s1t + a2e s2t + . . + an e sn t . (note that the si will be complex! ) input to a system with transfer function h(s). then, the output of the system is given by y(t) = a1h(s1)e s1t + a2h(s2)e s2t + . . + an h(sn )e sn t . consider a system with transfer function h(s) = s 2 + 1 1.5s and voltage input v1(t) = 4 cos(2t). we will find the output voltage v2(t) in three steps.
(a) write v1(t) in the form v1(t) = a1e s1t + a2e s2t + . . + an e sn t (i. e. write the cosine as a sum of complex exponentials.)
(b) use y(t) = a1h(s1)e s1t +a2h(s2)e s2t +. .+an h(sn )e sn t , with the specific h(s) above, to write v2(t) as a sum of complex exponentials.
(c) covert v2(t) back to be in the form of a cosine.
answer with explanation:
when dealing with heavy loads, one needs to take certain precautions in order to avoid or prevent from injuries.
for instance, one should avoid lifting above the shoulder level which can end up pulling your muscle.
also, you can either break the load in parts if possible or get some for lifting heavy bulks.
moreover, one should try to lift with the legs while keeping the back straight and not twisting it.
d is the answer
heat transfer through conduction is a slow process and both conduction and convection require material medium
you ruin your mop that way. it will clump up and than you'll have a mud mess.
