Define the DMA controller interface.
A DMA controller interfaces along with a few peripherals which may request DMA. The controller chooses the priority of simultaneous DMA requests communicates along with the peripheral and the CPU, and gives memory addresses for data transfer. DMA controller generally used with 8088 is the 8237 programmable device.
The 8237 is actually a special-purpose microprocessor. Normally this appears as part of the system controller chip-sets. The 8237 is a 4-channel device type. All channels are dedicated to an exact peripheral device and able of addressing 64 K bytes section of memory.

Q. Explain a common emitter configuration without a feedback. A simple common emitter transistor amplifier--having no negative feedback--is not an ideal amplifier. This is beca
Question: Consider the circuit shown in Figure. There is no initial energy stored in the circuit until time t=0 when the switch is closed. (i) Transform the given circ
Compute the mutual inductance: A long single layer solenoid has an effective diameter of 10 cm and it is wound with 1000 turns/m. There is a small concentrated coil with its p
For a discrete time unit step input x(kT), the output y(kT) of a system is shown below, Part (a) Obtain the Z-transform of the output signal y(kT). Part (b) F
Q. Why depletion MOSFET is known as "normally-on MOSFET" ? Draw the symbol of n-type and p-type depletion MOSFET. In depletion type MOSFET the drain current flows even when VGS
