Working around the impedance mismatch problem for object-oriented programs starts with recognition of the differences in the specific logic systems being employed. The mismatch is then either minimized or compensated for. The object–relational impedance mismatch problem is not a universal problem between OO and databases. As the name suggests, this impedance problem only occurs with relational databases. … WitrynaThe Impedance Mismatch. When a group of speakers’ total impedance is either higher or lower than the amplifier’s impedance range, an impedance mismatch occurs. …

WitrynaAn impedance mismatch in a circuit or along a transmission line will produce a reflection back to the source of the signal. When a signal reflects, the power transferred downstream towards a load is reduced. Impedance matching provides a dual role of enabling power transfer into a load by suppressing reflections.
