What is the number of vibrations that occur in one second?

Answer 1

That depends on what kind of a system the local oscillator is part of. In a simple AM receiver, it's typically 455 KHz above the frequency of the incoming signal of interest. In a consumer FM radio, that figure is 10.7 MHz above. In a 'legacy' analog microwave receiver, it's almost always spaced 70 MHz from the received carrier, and since the ubiquitous advent of split-mount digital microwave equipment, with the RF system clamped to the antenna, there's no telling any more ... you always have to look in the book (if that information is even included in the book).

Answer 2

Number of vibrations per second is frequency of vibrations. The same is also known as number of oscillations, number of repetitions, number of rotations, number of cycles, number of revolutions.

Answer 3

This question as stated is not answerable. The unit of frequency is the hertz and it is defined as one oscillation each second. Something that oscillates sixty times each second is said to oscillate at a frequency of 60 hertz.

Answer 4

In this diagram it is clear that time period is 1 second. Reciprocal of time period gives frequency. So frequency i.e the number of vibrations in one second is also 1. Its unit is hertz and denoted by Hz

Answer 5

The number of oscillations in one second is called a Hertz.

The old designation was a cycle, however it was renamed in honor of Heinrich Hertz.

Therefore, sixty cycles per second is now called 60 Hertz.

In musical terms, you will see 440 Hz. (A above middle C), which is the standard that most orchestras use as a reference.

Answer 6

The number of vibrations that occur in one second is known as the frequency, measured in Hertz (Hz). In the context of sound, humans can hear frequencies between 20 Hz and 20,000 Hz.

Answer 7

It's the frequency that oscillates a signal, most of the times, or just oscillating frequency of a signal, like a sine, cosine, a pulse etc.

Answer 8

frequency is the number of cycles per second

i.e. f=1/t

Answer 9

frequency.
Frequency can be the number of oscillations in any period of time. If your timebase is seconds, the frequency is measured in Hertz (cycles per second).

Answer 10

2,300 Hz = 2.3 KHz = 0.0023 MHz = 0.0000023 GHz
