Definitions:

T Filters

T filters are electronic filters consisting of two reactive elements separated by a resistor, forming a T shape, used in circuits to reduce noise or manipulate signal frequencies.

Bandwidth

The range of frequencies within a given band, particularly that used for transmitting a signal.

Tolerance

The amount of variation from a standard value that is permissible.

Impedance

The total opposition a circuit presents to the flow of alternating current, combining both resistance and reactance.
