<p>In <a href="page.php?w=electrical_engineering">electrical engineering</a>, <b>impedance matching</b> is the practice of designing or adjusting the <a href="page.php?w=input_impedance">input impedance</a> or <a href="page.php?w=output_impedance">output impedance</a> of an electrical device for a desired value.  Often, the desired value is selected to maximize <a href="page.php?w=Electric_power">power</a> transfer or minimize <a href="page.php?w=signal_reflection">signal reflection</a>. For example, impedance matching typically is used to improve</p><p>
