Choke transformers are sometimes called transmission-line transformers (although see below for a different transformer type with the same name), or Guanella transformers, or current baluns, or line isolators. Although called a "transmission line" transformer, it is distinct from the transformers made from segments of transmission line.
Transmission line or choke baluns can be considered as simple forms of transmission line transformers. This type is sometimes called a current balun, since it ensures equal current on both sides of its output, but not necessarily equal voltage. These are normally called ununs, because they go from unbalanced to unbalanced or un-un.
A circuit that has the specific purpose of allowing interfacing between balanced and unbalanced circuits is called a balun. A balun could be a transformer with one leg earthed on the unbalanced side as described in the transformer balance section above. Other circuits are possible such as autotransformers or active circuits. [4]
Pay the current balance: This covers your statement balance plus any charges you’ve made since the end of the billing cycle. It will bring your balance to $0, which is good, but not necessary to ...
This simple RF choke impedes signals passing on the outside of the braid, which helps to cure television interference. A braid-breaker is a filter that prevents television interference (TVI). In many cases, TVI is caused by a high field strength of a nearby high frequency (HF) transmitter, the aerial down lead plugged into the back of the TV ...
The current balance and available balance shown on the ATM screen or receipt should be the same as what you see when you log in to your account on the bank's website or mobile app.
A current balun uses a transformer wound on a toroid or rod of magnetic material such as ferrite. All of the current seen at the input goes into one terminal of the balanced antenna. It forms a balun by choking common-mode current. The material isn't critical for 1:1 because there is no transformer action applied to the desired differential ...
Unbalanced lines are to be contrasted with balanced lines, such as twin-lead or twisted pair which use two identical conductors to maintain impedance balance throughout the line. Balanced and unbalanced lines can be interfaced using a device called a balun. The chief advantage of the unbalanced line format is cost efficiency.
