How do you find the taper of a potentiometer?
How do you find the taper of a potentiometer?
The easiest way to determine if you have a linear taper is to place the shaft at the mid-point of the rotation and measure the resistance between the center terminal and either end terminal.
What is audio taper potentiometer?
Audio taper potentiometers are the potentiometers that are used for volume control in audio devices. This includes headphones, headsets, computer speakers, or any volume-altering devices. Most potentiometers used are linear tapers, meaning any turn in the wiper of the potentiometer changes the resistance linearly.
Are audio pots logarithmic?
To compensate for the ears logarithmic behavior, audio taper pots were developed. While it is called logarithmic, it is actually an exponential curve (the opposite of the logarithmic behavior of the human ear).
What is B taper potentiometer?
Potentiometers made in Asia and the USA are usually marked with an “A” for logarithmic taper or a “B” for linear taper; “C” for the rarely seen reverse logarithmic taper.
Is log taper the same as audio taper?
Glossary Term: Logarithmic-Taper When used in an amplifier circuit, the output varies slowly as the pot is operated at the low end and varies more and more rapidly as the pot is operated toward the high end. This is also called an audio taper because it is most commonly used for audio volume controls.
How do you read potentiometer markings?
Marking codes In this system the first digits indicate the value and the last digit indicates the multiplier. For example a 1 kΩ would be coded as 102, meaning 10 Ω x 102 = 1 kΩ. The taper of a potentiometer is normally indicated with a letter.
How do you tell if a potentiometer is audio or linear?
If there’s no marking on the pot, turn it to roughly half-way then measure the resistance between the wiper and each end. If they’re close, then it’s linear. If they’re substantially different, then it’s audio/log taper.
What are two types of taper in a potentiometer?
Potentiometer Taper Charts
- Linear Taper. = total resistance of the potentiometer, measured between the potentiometer hot and cold lugs.
- Audio Taper. = nominal resistance of the potentiometer, measured between the potentiometer hot and cold lugs.
- Reverse Audio Taper.
- M and N Taper (Blend-Balance)
Is an audio taper linear or nonlinear?
Non-linear tapers are often referred to as a logarithmic or audio taper. These are most commonly used for audio volume control.
