What is meant by electronic measurement? What are the characteristics of electronic measurement?
2. Electronic measurement in the narrow sense refers to the measurement of various electrical parameters in electronics.
The content of narrow electronic measurement mainly includes:
(1) the measurement of energy
The measurement of energy refers to the measurement of current, voltage, power, electric field strength and other parameters.
(2) Measurement of circuit parameters
Measurement of circuit parameters refers to the measurement of resistance, inductance, capacitance, impedance, quality factor, loss rate and other parameters.
(3)Measurement of Signal Characteristics
Measurement of signal characteristics refers to the measurement of frequency, period, time, phase, modulation factor, distortion and other parameters.
(4)Measurement of electronic equipment performance
Measurement of electronic equipment performance refers to the measurement of passband, selectivity, amplification, attenuation, sensitivity, signal-to-noise ratio and other parameters.
(5) Measurement of characteristic curves
Measurement of characteristic curves refers to the measurement of amplitude-frequency characteristics, phase-frequency characteristics, device characteristics and other characteristic curves.
The above parameters, frequency, time, voltage, phase, impedance, etc. is the basic parameter, the other for the derived parameters, the measurement of the basic parameters is the basis for the measurement of the derived parameters. Voltage measurement is the most basic and important measurement.
