Below is a list of key problem areas with correct and incorrect examples of each.
Use Words For... | Use Numerals For... |
---|---|
The first number in a phrase with multiple numbers (ten 6-bit buffers) | Units of measurement (5 centimeters, 8 picas) |
Fractions without a whole number (one-fourth, seven-eighths) | Fractions with a whole number (19 3/4 inches, 7 3/4 miles) |
Numbers with decimals (6.37) | |
Page numbers (Page 85) | |
Chapters (Chapter 3) | |

Incorrect: This system uses 2 bidirectional I/O ports, which are five-bit and eight-bit respectively (see Figures Nine and Ten below for illustrations).
Correct: This system uses two bidirectional I/O ports, which are 5-bit and 8-bit respectively (see Figures 9 and 10 below for illustrations).
NOTE: When a paragraph or other large section of writing contains a combination of numbers, write them all numerically.
ECE-Specific Conventions for Writing Numbers
The following are examples of number writing conventions specific to much of the ECE literature.
12. Always make sure to check for misspelled words in your writing. Do not rely upon spellcheckers because they may not catch all of your errors.
Incorrect: Analog signal processing acts faster than digitil signal processing.
Correct: Analog signal processing acts faster than digital signal processing.
Incorrect: In this lab, we preformed five separate experiments.
Correct: In this lab, we performed five separate experiments.
13. Correctly identify nouns and phrases using articles (a, an, and the).
Incorrect: With rapid increase in demand of portable devices, need for low-power devices has become important.
Correct: With the rapid increase in demand of portable devices, the need for low-power devices has become important.
14.Use first-person (I, me, my, we, us, our) with caution. Many readers find first-person inappropriate for professional writing, while others prefer it to wordier, less-specific phrases. In general, you should determine what is expected for your particular writing situation or your particular field. Also, ask yourself three questions about potential use of first-person:
Incorrect: I observed that neither of the two values correctly corresponds with the problem.
Correct: Neither of the two values correctly corresponds with the problem.
15. When using acronyms, define them before using the abbreviation.
Incorrect: BellSouth measures its QoS by the customer reaction to its new voice modulated devices.
Correct: BellSouth measures its Quality of Service (QoS) by the customer reaction to its new voice modulated devices.
16. Always use italics for variables in formulas.
Incorrect: k = C – 1
2m-length polynomials
Correct: k = C – 1
2m-length polynomials
17. Use hyphens between multiple-word adjectives that precede nouns. Omit hyphens with adverbs (these usually end in "-ly").
Incorrect: For low power designs, the dynamic power dissipation poses an application barrier.
Correct: For low-power designs, the dynamic power dissipation poses an application barrier.
18. Use that, which, and who appropriately.
That refers to objects and is restrictive - its meaning is essential to the sentence in question. Do not set off restrictive elements with commas.
Incorrect: The instruction encoding, that is used for the new microprocessor, is slightly modified.
Correct: The instruction encoding that is used for the new microprocessor is slightly modified.
Which refers to objects and is nonrestrictive - its meaning, though perhaps helpful, is not essential to the sentence in question. Set off nonrestrictive elements with commas.
Incorrect: The Hubble telescope which was intended to answer fundamental questions about the origin of the universe was repaired in 1997.
Correct: The Hubble telescope, which was intended to answer fundamental questions about the origin of the universe, was repaired in 1997.
Who refers to people and can be either restrictive (no commas) or nonrestrictive (commas) depending on its use.
Incorrect: Professor Smith who joined the faculty this year has introduced a new 8000-level graduate course. (Nonrestrictive - no need to distinguish between more than one Professor Smith)
Correct: Professor Smith, who joined the faculty this year, has introduced a new 8000-level graduate course.
Incorrect: The woman, who graded our lab reports, also led our tutoring sessions. (Restrictive - "woman" is too general and needs distinguishing)
Correct: The woman who graded our lab reports also led our tutoring sessions.
19. Maintain parallel structure by using the same grammatical form for coordinate sentence elements.
Incorrect: The sequence of events in asynchronous design are drawing a timing diagram, developing a flow table, doing state reduction, making state assignments, and to implement the design.
Correct: The sequence of events in asynchronous design are drawing a timing diagram, developing a flow table, doing state reduction, making state assignments, and implementing the design.
20. Avoid long noun strings. Break up long noun strings by putting some modifiers before the noun and some after.
Incorrect: This paper proposes a new fetching-stage-dedicated completion-detection method.
Correct: This paper proposes a new completion-detection method dedicated to the fetching stage.
21. Avoid unnecessary, repetitive prepositional phrases. In particular, use the possessive case when appropriate to avoid repetitious phrases with of.
Incorrect: The complexity of the module will hamper the ability of the operator in the diagnosis of problems in equipment configuration.
Correct: The module's complexity will hamper the operator's ability to diagnose equipment-configuration problems.
22. Avoid unnecessarily wordy phrases.
Incorrect: In the majority of cases, the data provided by direct examination of only the memory data bus using a logic analyzer are insufficient for the proper identification of microprocessor instruction execution.
Correct: Monitoring only the data bus usually cannot identify instruction execution.
