Q. Explain about Half Duplex Transmission?
Half Duplex Transmission
A half-duplex channel can receive andsend, though not at the same instance. It's like a one-lane bridge where two-way traffic should give way in order to cross. Only one end transmits at a time, the other end receives.
Q. Discuss the disadvantages of an RC coupled amplifier? RC coupled amplifiers have a few disadvantages. The resistors use dc power and so the amplifier has low efficiency. The
Vital parameters of regulator quality: 1. The output voltage's temperature coefficient of is the change in output voltage with temperature (perhaps averaged over a certain tem
Q. A 230-Vdc shuntmotor delivers 30 hp at the shaft at 1120 r/min. If the motor has an efficiency of 87% at this load, find: (a) The total input power. (b) The line current.
Q. What are the advantages of an RC coupling over a direct coupling? Draw a basic Rc coupling network and explain. Figure -RC-coupled transistor amplifier The network
The free electron theory of metals was first proposed by Drude and later improved by Lorentz. The main postulates of this theory are 1. All metal contain, adequate number
Data analysis in GIS: Therefore, GIS consists of the following: 1. Database - for storage and retrieval of information. The database forms the foundation of the GIS syst
STAX Store Accumulator Indirect Instruction This instruction is used to copy data from accumulator to the memory location pointed by register pair ( only BC or DE pair).
Explain Diffusion. Diffusion : Though, the mobility of the carriers in a semiconductor is greater than the electrons in metals, the conductivity in the former is much less t
Q. Write a note on the application of emitter-follower? An emitter follower can serve as a buffer for a voltage source. The voltage divider at left is a poor voltage source bec
Q. The line-to-line voltage of a balanced wye connected three-phase source is given as 100 V. Choose V AB as the reference. (a) For the phase sequence A-B-C, sketch the phasor
