The accuracy of a 4-20 mA transmitter depends on the integrity of its current-loop path, which must be free of shunt paths and ground loops, both within the transmitter and external to it. External to ...

Tactical military radio requirements have seen significant changes over the last several years. In order to meet the communication needs of Future Combat Systems, programs like the Joint Tactical ...

The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

The mode of operation of the amplitude-modulated transmitter Class-C output stage is discussed, with particular references to the case where the load impedance varies over the working frequency band; ...

Promising to ease the design of smart transmitters in two-wire sensor systems, the DAC161P997 d/a converter sports a single-wire interface and 4-mA to 20-mA current loop drive. Its delta-sigma DAC ...

Handset manufacturers play an equally important role in this consumer equation by providing reliable, cost-effective handsets that are usable across multiple operating standards and market spaces. In ...
