Discuss DMA definition.
Direct memory access (DMA) is a process wherein an external device takes over the control of system bus by the CPU. Direct memory access is for high-speed data transfer by mass storage peripherals, for illustration magnetic tape, hard disk drive, CD-ROM and sometimes video controllers. For instance, a hard disk may boast a transfer rate of 5 M bytes per second, which is 1 byte transmission every 200 ns. To make that data transfer with the CPU is both undesirable and unessential.

design a clipper circuit of a sinsoiudial wave of a peak value 25v&minimum value of -12v to make the output voltages of 20&-9v respectively.
Explain the term simplex transmission. Data in a simplex channel is always one method. Simplex channels are not frequently used because this is not possible to send back error

Define Quantization Error? Quantization by its nature introduces errors. There are two major sources of errors. One is sampling, that just takes the amplitude of the signal at
