The range of signal generating frequencies for a function generator is __________.
0.01 kHz to 100 Hz
0.01 Hz to 100 Hz
0.01 kHz to 100 kHz
0.01 Hz to 100 kHz
0.01 Hz to 100 kHz
A function generator is an electronic test instrument used to generate different electrical waveforms such as sine, square, triangular, and saw-tooth waves. Standard general-purpose function generators typically cover a broad frequency spectrum, usually ranging from very low frequencies (milli-Hertz) up to the high-kilohertz range.

The generator typically uses an internal oscillator circuit, often involving a capacitor charging/discharging cycle controlled by constant current sources. By adjusting the current I and the capacitance C in the expression f=4CVpтАЛIтАЛ, where VpтАЛ is the peak voltage, the output frequency can be precisely tuned across the design range.
Function generators are essential for testing frequency response of circuits.
They provide variable frequency, variable amplitude, and variable offset voltage.
Commonly used in laboratories for educational and research purposes.
Capability to produce multiple standard waveforms.
High precision in frequency selection across decades.
Adjustable output impedance for impedance matching.
Limited frequency response at very high RF frequencies.
Susceptible to harmonic distortion at extreme ends of frequency bands.
Audio frequency testing
Circuit characterization
Testing of communication systems
The range 0.01 Hz to 100 kHz covers the entire audible frequency spectrum and beyond, making it standard for audio engineering and basic electronics.
Options A, B, and C fail to represent the wide, commercially standard dynamic range of typical laboratory-grade function generators.
D is correct тАФ The standard frequency range for a general-purpose laboratory function generator is 0.01 Hz to 100 kHz.
Remember that function generators focus on versatility (multiple waves), whereas signal generators (RF) focus on high-frequency precision (sine waves only).
