A distortion meter is a type of
electronic test equipment
Electronic test equipment is used to create signals and capture responses from electronic devices under test (DUTs). In this way, the proper operation of the DUT can be proven or faults in the device can be traced. Use of electronic test equipmen ...
used to determine specific
frequencies
Frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as ''temporal frequency'' for clarity, and is distinct from ''angular frequency''. Frequency is measured in hertz (Hz) which is eq ...
that cause distortion in electronic devices. The device is primarily used in
audio related equipment.
Features and uses
A typical unit injects a
signal
In signal processing, a signal is a function that conveys information about a phenomenon. Any quantity that can vary over space or time can be used as a signal to share messages between observers. The ''IEEE Transactions on Signal Processing'' ...
in to the input of a circuit and monitors the output of the circuit for distortion.
Types of Distortion
1) Amplitude distortion.
2) Frequency distortion.
3) Phase distortion.
4) Intermodulation distortion.
5) Cross over distortion.
