You can represent 8 on a digital computer in several different ways. One way is to use 7-bit ASCII encoding: __________. Another is to convert the number to its binary equivalent: __________. 

Which of the two frequencies will provide a more reliable connection in an environment in which there are many geographic obstacles, such as hills and valleys?

Compare two carrier frequencies, one at 89.7MHz and the other at 2.4GHz, in terms of the information they can convey.  You may assume that each signal is transmitted over a dedicated wire. Which carrier can be used to convey more information given a signal with a 100kHz bandwidth?

How would recording (i) with a sampling rate of 20kHz recorded and using 8 bits/sample differ from recording (ii) with a sampling rate of 20kHz and using 16 bits/sample?

[i] Time-division multiplexing (TDM) is different than frequency-division multiplexing (FDM) because [ii] FDM is based on frequency modulation and TDM shares the channel by dividing it into short timeslots.

Calculate message latency for a 25 Kbit message with a bitrate of 100 Kbits/second and a propagation delay of .25 seconds.  Show your calculations and remember to indicate the unit of measurement for all quantities.

What can we do to fix the aliasing shown in the picture of a barn door?

Suppose parity(bitstring) is equal to 1 if there are an odd number of ones, otherwise it is 0.  If a host receives the bitstring 101011011, what does it mean, and should happen next?
