Extra exam question E5C04
Subelement E5, ELECTRICAL PRINCIPLES· Group E5C
What type of Y-axis scale is most often used for graphs of circuit frequency response?
- A.Linear
- B.Scatter
- C.Random
- D.Logarithmic (correct answer)
WhyGraphs of circuit frequency response most often use a logarithmic Y-axis scale. Circuit frequency response graphs commonly use a logarithmic Y-axis scale, since signal levels in a frequency response often span many orders of magnitude and a log scale (often in dB) compresses that huge range into something readable on a single graph, answer D. Linear, scatter, and random scales aren't the standard choice for this kind of plot.
