Multiple-choice practice for signal generator topics

Function generators, arbitrary waveform generators and RF sources show up in most electronics and signals courses, and the exam questions often test specific settings like amplitude, offset and duty cycle. Instead of a fixed printable worksheet, DeckOwl builds MCQs on signal generators from the material you already have, so the questions follow your syllabus.

Example MCQ questions on signal generator basics

What is the difference between amplitude and peak-to-peak voltage on a sine wave?Peak-to-peak spans from the negative peak to the positive peak, so for a symmetric sine wave it is twice the amplitude.

A square wave is set to a 50% duty cycle with no DC offset. What is its average voltage?Zero, because the signal spends equal time at its high and low levels, so the positive and negative areas cancel.

Why does a signal generator show about double the voltage when its output is left open-circuited?The displayed amplitude assumes a 50 ohm load, and without that load the source impedance no longer drops half the voltage.

What does the DC offset control on a function generator do?It shifts the whole waveform up or down so the signal rides on a DC level, which is needed to bias transistor inputs.

What can an arbitrary waveform generator produce that a standard function generator cannot?A user-defined waveform loaded from memory, rather than only the fixed sine, square and triangle shapes.

Questions from your material

Your own course notes or slides are the source, so the questions match what your instructor actually covered.

Explanations for every answer

Each question shows why the correct option is right, which helps when a wrong choice looked plausible.

Exports when you need them

Paid plans export to PDF, DOCX, Anki and CSV. Pro adds QTI 2.1 and Moodle XML for course platforms.

How it works

Upload your material

Add a PDF, DOCX, PPTX, plain text notes or a photo of a page.

Choose the question type

Pick multiple choice, true/false or short answer, then generate the set.

Practice in the browser

Answer the questions, read the explanations and review the ones you missed.

Upload your lecture slides or notes and DeckOwl writes multiple-choice, true/false or open questions, each with an explanation of the correct answer. You can work through them in the browser on the free plan, which includes 3 generations per month.

If your instructor needs the questions in a learning platform, Pro exports QTI 2.1 and Moodle XML, while Plus exports PDF and DOCX for handouts and printed practice sheets.

Frequently asked questions

What is the difference between amplitude and peak-to-peak voltage on a signal generator?

Amplitude is measured from the zero line to the peak, while peak-to-peak spans from the lowest point to the highest point. For a symmetric waveform with no DC offset, peak-to-peak is twice the amplitude.

Why do signal generators have a 50 ohm output impedance?

The 50 ohm output matches the standard impedance of most coaxial cables and test equipment, which avoids reflections. The displayed amplitude usually assumes a 50 ohm load, so an open circuit will show about double the voltage.

Is there a free plan, and can I export questions from it?

The free plan includes 3 generations per month and studying in the browser, but exports are not included. PDF, DOCX, Anki and CSV export start on the Plus plan.

Can I export these MCQs to Moodle?

Yes, Moodle XML export is included on the Pro plan at $14.99/month. Students with a school email get 40% off paid plans.
