"Reel", "slip jig", "hornpipe", and "jig" are all types of Irish stepdances and are also types of Irish traditional
Transformer types impedances between circuits over a limited range of frequencies, using only a length of transmission line. The line may be coaxial cable, waveguide, stripline, or microstrip. Baluns are transformers designed specifically to connect between balanced (non-grounded) and unbalanced (grounded) circuits. These are sometimes made from configurations of transmission line and sometimes bifilar or coaxial cable and are similar to transmission line transformers in construction and operation. Baluns can be designed to not only interface between balanced and unbalanced loads, but to additionally provide impedance matching between those load types. Ferrite-core transformers are widely used in (intermediate frequency) (IF) stages in
