In the
center tap coupled method, the input coupling strength is controlled by the change in the step impedance from the feed-line to the square patch line impedance.
Three tap configurations are available: basic four lead, five lead with a secondary
center tap and six lead with primary and secondary
center taps.
Specifications of the potentiometer include an electrical angle of 340[degrees], an output smoothness of 0.1%, an absolute linearity of [+ or -] 0.5 at
center tap and a resistance range of 1000 [ohm] to 20,000 [ohm] [+ or -] 10%.
In an amplifier, a large metallic bus bar carries the ground current from the speaker to the
center tap of the transformer; the metal attempts to keep the output ground to the
center tap ground the same.
The Endspan is a switch that integrates the PoE source, to simplify the infrastructure, using phantom feeding on the
center tap of the Ethernet pulse transformer.
The 16-b NI PXI-6704 static analog output module, for example, can provide the DC level via the
center tap of the secondary transformer.
Shortly after the
center tap, Johnson buried a 17-footer and then followed with a 3-pointer.
Whenever possible, choose a signal source with low impedance, as well as a
center tap on its output.
Amplitude balance, sometimes called "unbalance", is the absolute value of the difference in signal amplitude, in dB, between the two outputs of a center-tapped transformer using the
center tap as a ground reference.
* Non-Torque, Extended Range, Close
Center Tap Adaptor - used where close center tapping with large tap sizes prohibits use of other tap adaptors.
Designed for use in feedback circuits in amplifiers requiring ratio matching, high power and tracking between two resistors, the CTN resistors are capable of operating as a single-value resistor or as two resistors with a
center tap feature.
