PRACTICE MATCHING LOADS TO POWER SOURCES IN ENGINEERING
Impedance match; Impedance mismatch; Matching network; Mismatched impedance; Mismatched impedances; Impedence matching; Line impedance; Impedance-matched
In electronics, impedance matching is the practice of designing or adjusting the input impedance or output impedance of an electrical device for a desired value. Often, the desired value is selected to maximize power transfer or minimize signal reflection.
