Meaning and Definition

An electronic device or circuit that produces electronic signals (usually repeating waveforms like sine, square, or sawtooth waves) for the purpose of testing, repairing, or designing other electronic equipment.

More broadly, any device, system, or software that creates and outputs a controlled signal. This can be abstracted to include non-electronic contexts, such as a person or process that initiates a sign or cue.

Dialectal Variation

Common Mistakes When Using “signal generator”

  • Mispronouncing 'generator' with a soft 'g' (/dʒ/) as in 'general'. It should be /ˈdʒɛnəreɪtə/.

  • Confusing it with a 'power generator' or 'signal booster'.

FAQ

Frequently Asked Questions

A function generator is a common type of signal generator that produces specific, standard waveform functions (sine, square, triangle). 'Signal generator' is the broader category, which includes function generators, RF signal generators, and arbitrary waveform generators.

Yes, to a limited extent. There are apps that can output audio-frequency tones through the headphone jack, effectively acting as a basic, low-frequency audio signal generator. They lack the precision, power, and frequency range of dedicated hardware.

Its primary purpose is to be a known, controlled source of a signal. This allows engineers to test, calibrate, and debug electronic devices by seeing how they respond to a specific input, isolating problems from unpredictable real-world signals.

RF stands for Radio Frequency. An RF signal generator is designed to produce signals in the radio frequency spectrum, which is crucial for testing wireless communication devices like radios, mobile phones, and WiFi routers.

An electronic device or circuit that produces electronic signals (usually repeating waveforms like sine, square, or sawtooth waves) for the purpose of testing, repairing, or designing other electronic equipment.

Signal generator is usually technical, formal. in register.

Signal generator: in British English it is pronounced /ˈsɪɡnəl ˈdʒɛnəreɪtə/, and in American English it is pronounced /ˈsɪɡnəl ˈdʒɛnəreɪtər/. Tap the audio buttons above to hear it.

Mnemonic

Think of a 'SIGNAL' traffic light. A GENERATOR makes electricity. A SIGNAL GENERATOR is a device that 'makes' or 'generates' electronic 'traffic lights' (signals) for other machines to read.

Conceptual Metaphor

A FOUNTAIN or SOURCE. The signal generator is conceptualised as a controlled source from which signals (like water) flow.
