ENGR 217 Final Exam Review
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
