Questions Complete Solutions Correct
Update 2025/2026
Binary to Hexadecimal - ANS ✔✔Combine each group of four binary bits into a single
hexadecimal digit using the 8421/8421 rule.
Binary to Decimal - ANS ✔✔Multiply by powers of 2 beginning with the rightmost digit
Largest digital value that can be output by a 16 bit ADC - ANS ✔✔2^n - 1 = 65,535
How does a Flash type ADC work? Pros and cons? - ANS ✔✔Makes every single comparison at
one time.
Pro: extremely fast
Con: takes a lot of hardware
What is successive approximation? Pros and cons? - ANS ✔✔Similar to bi-section numerical
method.
Pro: small amount of hardware
Con: slower
Explain how a DAC works - ANS ✔✔A ladder of resistors and a decoder convert the input digital
value to turn on the correct switch.
Finite Differences - ANS ✔✔ΔΦ/Δx
(Φ left-Φ right)/(x left-x right)
, rules for project network diagram.
What is the critical path? - ANS ✔✔Forwards- adding; take largest value when combining.
Backwards-subtracting; take smallest value when combining.
Critical path- when the top and bottom are the same values.
Calculate the EMF of a D.C motor - ANS ✔✔E = (Φ * P * N * Z) / (60 * A)
or
everything over (60 * A)
Solving for R in electrical circuits - ANS ✔✔series: R = R1 + R2
Parallel: 1/R = 1/R1 + 1/R2
What is the four materials displayed in Daniel Rozin's work "Materials and Engineering" - ANS
✔✔Wood (Would)
Brass (Brad)
Stainless Steel (Suck)
Circuit Board (Cock)
Micro-controller (physical) - ANS ✔✔On-board ROM to hold program being run.
On-board RAM to hold program variables.
Built in I/O.
Modern micro-controllers will have a bus.
Micro-Controller (how they are used) - ANS ✔✔Designed to hold and run only one program.
Within program, runs the loop function continuously.
No operating system.
