Question

Write short note on foundation field bus.

Answer 1

The primary function of terminators is to act as a current shunt for the control network. Fieldbus communication works by the field device modulating its current draw. When the devices need to transmit data, the FF devices will act as a current sink.

Maximum Devices: 32 no

des/segment

Type of Network: Process Control

Maximum Distance: 9500 meters with 4 repeaters(depending on minimum signal str.

Device Addressing: Automatic when connected to segment.

Hope this helps ☺️☺️

Answer 2

Graphic and parametric equalizers have much more flexibility in tailoring the frequency content of an audio signal. Since equalizers "adjust the amplitude of audio signals at particular frequencies," they are, "in other words, frequency-specific volume knobs."
