Frequency FAQs:

Q: Is frequency the number of occurrences of a repeating event per unit time?

A: Yes.

Q: Are frequencies usually measured with a frequency counter?

A: Yes.

Q: Is frequency the property of sound that most determines pitch?

A: Yes.

Q: Is frequency analogous to temporal frequency?

A: Yes, but the time axis is replaced by one or more spatial displacement axes.

Q: Is frequency commonly measured in radians per second but?

A: Yes, for discrete-time signals, can also be expressed as radians per sample time, which is a dimensionless quantity.

Q: Is frequency the hertz , named after the German physicist Heinrich Hertz?

A: Yes, one hertz means that an event repeats once per second.

Q: Is frequency mixed with the unknown frequency in a nonlinear mixing device such as a diode?

A: Yes.

Q: Is frequency an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena?

A: Yes, such as mechanical vibrations, audio signals, radio waves, and light.

Q: Is frequency defined as a number of cycles per unit time?

A: Yes.
