1 (20 pts) You are working for NASA/JPL on the Juno mission. Juno is a large spacecraft orbiting Jupiter.
It's current distance from Earth is 536 million miles. Assume the speed of light is c = 2:0 108 m/s. The
transfer rate from Juno to Earth is 50 Mbps. The frame is made up of a 24 byte header plus a variable size
payload of 1 - 1000 bytes. Answer the following:

(a) The total transmission time to send 128 GB of pictures to Earth. Assume only transmission time and
propagation delay.
(b) The amount of time required to transfer the pictures taking in to account propagation delay, transmis-
sion delay, queuing delay, and processing delay. Queuing delay is 1 ms per frame and processing delay
is 0.5 ms per frame

Q2) (a) construct a truth table for the following function: ?(?, ?, ?) = (?? + ?̅?) ̅̅̅ + ??

(b) Use the truth table of (a) to write the function F in sum of minterms form.

You are working on the design of a new hybrid-electric experimental airplane that uses six 12-volt batteries in series. During integration testing, results indicate there is unexplained drain on the batteries. The first step in troubleshooting is to analyze the circuit that may be modeled as three resistors in series, R1 (10 Ω ), R2 (12 Ω ) , and R3 (18 Ω ). Find the total resistance. Calculate the total current. Find voltage across each resistive element. Calculate the power delivered by the batteries. Find the power delivered to the 18Ω . In addition to the above calculations, explain to a member of upper management why better understanding of this circuit by calculating these values may be beneficial to the future design.
