Essential Excel Formulas Every Engineering Team Should Know

You do not need hundreds of functions to work well in Excel. A small group of Excel formulas for engineers covers most daily tasks, from summarising test results to tracking project costs.

Summing and counting with conditions

SUMIFS adds values that meet one or more conditions, for example total cost for one vendor in one month. COUNTIFS counts matching rows, such as the number of open issues for a given project.

Looking up values

XLOOKUP finds a value in one column and returns a match from another. It is available in current Microsoft 365 and recent Excel versions. In older versions, INDEX with MATCH gives the same result and is very reliable.

Handling errors and decisions

  • IFERROR replaces error results with a clear message or blank
  • IF returns different results based on a test
  • AND / OR combine several conditions

Working with dates and text

TODAY and DATEDIF help with deadlines and ageing. TEXT formats numbers and dates inside labels, while CONCAT or TEXTJOIN joins pieces of text.

Statistics for test data

AVERAGE, MEDIAN, STDEV.S, MIN and MAX give a quick picture of any data set. Use them before drawing charts so unusual values are noticed early.

Common Mistakes to Avoid

  • Using VLOOKUP with approximate match by accident
  • Copying formulas without checking cell references
  • Hiding errors with IFERROR instead of fixing them
  • Applying XLOOKUP in files shared with users on older versions

Frequently Asked Questions

Is XLOOKUP better than VLOOKUP?

It is more flexible, since it can look left and defaults to exact match. It needs a recent Excel version, so check your colleagues' versions.

When should I use INDEX with MATCH?

When you must support older Excel versions or want a lookup that does not break when columns are inserted.

What does SUMIFS do?

It adds numbers that meet one or more conditions, such as total spend for a given vendor in a given month.

  VLSI design of median filter Filters are linear systems employed for removal of noise from useful signals. Conventional IIR filters and FIR filters are highly envolved. In general They are computional algorithms requiring definite delay between input and the outputs. However long tailed noise such as exponentional and laplasion distribution noise are difficult to remove using conventional linear filters. Median filters are a class of non linear filters having advantages 1.    Capability to remove long tailed noise 2.    Capability to preserve edge information   The most desirable property of median filters is that they are based on signal “sorting and selection operations”. No Computation is involved. Therefore, they are the most suitable for real time VLSI. Uses 1.    Image processing 2.    Communication networks
