Explain RS422A standard.
RS422A:
1. Date Rate: 10 Mbits per second
2. Driving capability up to 4000ft and 10 receivers
3. This is Differential standard that is- all signals are represented with a pair of wires and voltage difference across these wires is sensed at the receiver.
This minimizes the result of ground noise or the voltage drop beside the signal leads.
4. Signal levels are: from -2 to -6V and from +2 to +6V.
Explain Open Loop Control Systems In an open-loop control system, the controller independently computes exact voltage or current required by the actuator to do the job and send
An electric heater element is made of Nichrome wire having resistivity equal to 100 ×10 -8 ohm-metre. The diameter of the wire is 0.3 mm. Calculate the length of the w
Demand Meters Demand meters measure volt-amperes (in kVA), that merge both reactive (reflected) and actual (consumed) power. In its easiest form, a demand meter has a gauge wh

Q. What do you mean by Inaccessible area coverage? Marshy lands, hilly areas, etc where ground surveys could be very difficult, remote sensing technique can provide reliable an
Question: a) Differentiate between Asynchronous message passing and Synchronous-message passing. b) If keyboards are the predominant means of interface to human input, the
Diac Diac is a device which has di electrode and as its name suggests it works on AC. The cross sectional view of a diac is shown if the four layers are PNPN and PNPN .
Ac power has significant practical advantages over dc power in generation, transmission, and distribution. One major drawback of the single-phase circuit is the oscillatory nature
