Question 4 (35 points). Two message signals, ?1 (?) =
200??(100??) cos(103πt) volts and ?2 (?) = 900??2 (450??)
cos(103πt) volts, are required to be combined and then transmitted
over a channel around 2 MHz using amplitude double-side modulation.
We assume that the channel is ideal with no delay and no
attenuation. Design a system consisting of mixers, filters, etc. to
transmit and restore perfectly these two signals (i.e. ?1 (?) and
?2 (?)) at the receiving side after the...

Prepare a design for the Baby Block Robot. The design should be in flow diagram form. This diagram should help you identify the sequence of steps needed to solve specific situations that the robot will encounter. Be specific. Break down the actions into small steps. Test you design by using example block sequences. Think it through. I would expect the diagram to require multiple pages. If you have a program that supports flow diagrams, like PowerPoint, then use that. Hand...
