What Is a Frequency Meter?
A frequency meter is an electronic device or component that outputs frequency as a number, also called a frequency counter. It measures the number of periodic pulses of an electrical signal and outputs the frequency.
Frequency meter is measurement instruments used in many applications related to high-frequency radio technology to measure frequency signals with high accuracy. Frequency meter is widely used in various areas of electrical testing to measure the frequency of repetitive signals.
Uses of Frequency Meters
Frequency meters are used by many researchers and engineers.
In addition to frequency measurement, frequency meters have various functions such as periodic measurement, additive measurement, and RPM measurement of one-minute values. They also have a low-pass filter function to cut off noise, since the input of noise will result in the output of incorrect frequencies.
With these features and functions, it is used not only for acoustic measurement systems but also for the frequency measurement of vibrating objects emitting ultrasonic waves.
Principle of Frequency Meters
Here we introduce the measurement principle of frequency meters.
A sinusoidal signal is expressed in terms of three parameters: frequency, amplitude, and phase. In addition, the pulse spacing is very important for digital signals. Frequency meters are designed to measure frequency and time.
The frequency meters consist of a waveform shaping section, a gate section, a reference time pulse generator, and a display section. First, the input signal is shaped into a pulse train in the waveform shaping section. The reference time pulse generator generates pulses with a precise time width of 0.1 or 1 second. The gate section switches the input signal shaped into a pulse train with pulses having this time width. The number of pulses obtained here is processed and output to the display section. For example, if the time width is 1 second and the number of input pulse trains is 10, the frequency is 10 Hz.
Because of this principle, care must be taken when measuring, because if noise is included, the pulse waveform may become unstable and the wrong frequency may be measured.
How to Use Frequency Meters
There are two main uses for frequency meters.
One is to check the performance of an oscillation circuit and is called a frequency counter. This device displays the frequency digitally.
It is used as a monitor to adjust the oscillation frequency to a predetermined value or to check the oscillation stability (frequency jitter). A multi-function frequency counter that can measure not only frequency but also period, duty, etc. is called a universal counter. Some models are equipped with this function as a function of a multimeter.
Another use of frequency meters is for vibration and acoustic measurements. In this application, the input signal is Fourier transformed and displayed graphically as a spectrum.
Acoustic Measurement with Frequency Meters
In an acoustic space, frequency meters are used as monitors to check the reflection and absorption of sound to create a uniform sound field, or to check the strength and frequency of vibrations emitted from equipment.
For example, in a car interior, a complex acoustic space is created by sound reflection from the windshield and rear glass, sound absorption from the seats and floor, and engine noise.
To create a comfortable sound, frequency and signal intensity distribution are checked with frequency meters, and an equalizer is used to strengthen or weaken highs and lows to create a comfortable acoustic space.
As another acoustic measurement, a sound level meter is also a kind of frequency meters. It is used to measure noise frequencies and sound pressure that affect the human body and to maintain an environment that does not cause physical modifications.
Frequency Meters Application
Frequency meters come with an application that not only quantifies the frequency of the input signal but also graphs it.
While the numbers alone do not allow you to check for wobble or noise components, the FFT operation allows you to isolate the frequency components and graph the intensity of each.
Applications are provided to express signal quality in an easy-to-understand visual manner, such as displaying the strength of side lobes that appear next to the main signal, averaging the input signal to remove abrupt noise for accurate measurement, and expressing the wobble of the signal in shades of color.
