What is the frequency of AC signals in the United States?

• 50 Hz

• 60 Hz

• 100 HZ

This circuit is of what order?

• 5th

• 3rd

• 2nd

The law stating that the direct current flowing in a conductor is directly proportional to the potential difference between its ends is:

• Ohm's Law

• Ampere's Law

• Faraday's Law

What year was IEEE formed?

• 1906

• 1941

What’s the difference between a union and a struct in C/C++?

• Structs can change all its memory by changing one variable while unions can change a chunk of its memory by changing one variable.

• Structs allocates variables in memory as a chunk while unions allocate variables in one piece of memory.

• Structs are like classes with private variables and unions are like classes with public variables. 

Which of the following is not a version of the Arduino? 

• Tre

• Galileo

• Zero

Used in wireless communications, what is the modulation technique called for this signal? 

• Phase Shift Keying (PSK)

• Amplitude Shift Keying (ASK)

• Frequency Shift Keying (FSK) 

What is the name of this logic gate?

• AND

• NAND

• XOR

Using the right-hand rule, which direction is the current flowing?

• To the left

• To the right

• out of page

Based off of Nyquist’s Theorem, how much faster should you sample your signal? 

• 2x the frequency

• 4x the frequency

• 16x the frequency
