o Semiconductor materials are often called solid-state devices<br />
• Three-phase Rectifier<br />
o Commonly used to change AC electricity into DC electricity<br />
16. Power Supply Circuit / Filters<br />
<strong>NCATT</strong> Level A<br />
Outcome: A successful education or training outcome for this task/subject will produce an<br />
individual who can identify basic facts and terminology related to power supply circuit filters.<br />
Power Supply Circuit Filters:<br />
Individuals should be able to explain the use and operation of power supply circuit filters with<br />
reference to the following terms:<br />
• Active filters—Produces a current or voltage gain<br />
• Passive filters—Produces no gain in an electrical circuit<br />
17. Frequency Sensitive Filter - Theory of Operation<br />
<strong>NCATT</strong> Level A<br />
Outcome: A successful education or training outcome for this task/subject will produce an<br />
individual who can identify basic facts and terminology related to frequency sensitive filter<br />
theory of operation. The following is a minimum list of terms and task associated with this<br />
subject.<br />
Theory of Operation:<br />
Individuals should be able to explain the use and operation of frequency sensitive filters with<br />
reference to the following terms:<br />
• Band-pass<br />
o Passes certain bands of middle frequencies while attenuating high and low<br />
frequencies through the use of resonant circuits<br />
• Band-reject<br />
o Attenuates a certain band of middle frequencies while passing the high and low<br />
frequencies through the use of resonant circuits<br />
• Cutoff Frequency<br />
o Frequency at which attenuation starts to increase rapidly<br />
• Demodulation<br />
o Electronic filter that decreases the amplitude of some frequencies relative to other<br />
frequencies<br />
• Detection<br />
o Another term for demodulation<br />
