Question:If you have two functions F(a,b,c) and G(a,b,c) to implement, what mux size and how many muxes would you need to implement F & G?My Comments:Is it as simple as using two 4-1 multiplexers because it will handle the 6 inputs? Or am I not understanding the function of a multiplexer?

How does the choice between analog and digital communication affect the design of a communication system?

Which controller gives no output for a constant input signal? O a. Integral O b. Derivative O. Proportional derivative O d. Proportional Which technique is used to record the data on a special paper ? O a. Impact Printing O b. Thermal Technique O. Moving coil Meter O d. Ink Pen Technique Successive approximation type ADC is used in most of the applications. Select one: O True O False

Determine the strength value for the proportional controller (error) and Integral Controller (sum of errors) Note: provide step by step strength calculation   error: NE = 0.5Z=0.5PE =0 Sum of errors: NE = 0 Z = 0.2 PE = 0.8

A multiplexer is a device that selects one among N analog or digital inputs and forwards the selected input to a single output line. Answer the following questions. (Note: You should show all the steps) a) If the mux has 4 inputs, how many control inputs are needed?    b) Draw the truth table of 4-to-1 multiplexer.

If the circuit given above is an array of sensors, what is the output function?
