• Resistor–transistor logic — (RTL) is a class of digital circuits built using resistors as the input network and bipolar junction transistors (BJTs) as switching devices. RTL is the earliest class of transistorized digital logic circuit used; other classes include… …   Wikipedia

• Cathode bias — In order for a vacuum tube (or valve) to operate in a fairly linear region of its characteristic curve, the grid element must be maintained at a bias voltage more negative than the cathode. This is called cathode bias.Early techniquesEarly… …   Wikipedia

• Grid bias — is a DC voltage applied to electron tubes (or valves in British English) with three electrodes or more, such as triodes. The control grid (usually the first grid) of these devices is used to control the electron flow from the heated cathode to… …   Wikipedia
