Homework Statement
Using the CTFS table of transforms and the CTFS properties, find the CTFS harmonic function of the signal
2*cos(100*pi(t - 0.005))
T = 1/50
Homework Equations
To = fundamental period
T = mTo
cos(2*pi*k/To) ----F.S./mTo---- (1/2)(delta[k-m] + delta[k+m])

An example:
A car that senses if you have your seat belt on and the door is closed
I can declare:
D - for door
S - for seat belt
D is 1 is door is open, 0 if door is closed
S is 1 if seat belt is on, 0 if it's off
This is all very straight forward and can be implemented with combinational...
There is this commercial where a guy was falling asleep in physics class, the professor calls his name and asks him what's the answer to a theoretical problem the professor has on the board. The guy looks around confused, sees someone in front of him with the number 7 on his back, so he says the...

ignore how many fleas are infesting the elephant. for this problem we're supposed to assume it is infested with 30,000 fleas and they all jump off the elephant in the same horizontal direction with the same speed and at the same time
Homework Statement
A flea infested elephant with a mass of 3500 kg is standing on a frozen lake wearing frictionless ice skates. If 30000 fast fleas jump off the elephants back (in a horizontal direction) per second, and each flea jumps with a velocity of 10 m/s find the velocity of the...
