A Motorola T-1300 series remote control is built in a telephone housing. The telephone dial is replaced with a metal plate on which is mounted a speaker, volume control and option switches. This remote control uses a two-wire circuit to control a base station. A General Electric MASTR II remote control and desk microphone.
A typical example are Howland current source [2] and its derivative Deboo integrator. [3] In the last example (Fig. 1), the Howland current source consists of an input voltage source, V IN, a positive resistor, R, a load (the capacitor, C, acting as impedance Z) and a negative impedance converter INIC (R 1 = R 2 = R 3 = R and the op-amp).
Current mode logic (CML), or source-coupled logic (SCL), is a digital design style used both for logic gates and for board-level digital signaling of digital data. The basic principle of CML is that current from a constant current generator is steered between two alternate paths depending on whether a logic zero or logic one is being represented.
no current means receive on channel 1, (the default). +6 mA might mean transmit on channel 1; −6 mA might mean stay in receive mode but switch to channel 2. So long as the −6 mA current were present, the remote base station would continue to receive on channel 2. −12 mA might command the base station to transmit on channel 2.
The current being "copied" can be, and sometimes is, a varying signal current. Conceptually, an ideal current mirror is simply an ideal inverting current amplifier that reverses the current direction as well, or it could consist of a current-controlled current source (CCCS). The current mirror is used to provide bias currents and active loads ...
A simple electric circuit made up of a voltage source and a resistor. Here, =, according to Ohm's Law. In the theory of electrical networks, a dependent source is a voltage source or a current source whose value depends on a voltage or current elsewhere in the network. [1]
To control these parameters more accurately, some fixtures use two channels for parameters that require greater accuracy. The first of the two channels controls the coarse (256 steps for the whole range of movement) and the second the fine (256 steps for each coarse step), this gives a 16-bit value range of 65536 steps, permitting much greater ...
