One period of a real-time signal x(t) =2Sin(20*pi*t) , starting at t=0, has to be processed in a 4-bit digital computer. The A/D card have a sampling frequency of 55Hz and the input range is +/- 2Volts.

i) What are the values recorded in the sampled signal x[n] ?

ii)What is the resulting quantized signal?

iii)What is the resulting digitized/coded signal?

iv)If the sampled signal x[n] was filtered using a moving average filter of length 3 , what would the filtered signal be?

Starting at time t=0, net force F1 is applied to an object that is initially at rest. If the force remains constant with magnitude F1 while the object moves a distance d, the final speed of the object is v1. What is the final speed v2 (in terms of v1) if the net force is F2=2F1 and the object moves the same distance d while the force is being applied? Express your answer in terms of v1.
