Answer

A multiplexer is a combinational (selection) device..which selects one of the many inputs by using a select signal and gives only one output..

Answer

D FF is a single bit memory cell. It is used to store one bit data. It is one of the most widely used flip flops in any VLSI circuit design. Accepts new signal values once the clock edge arrives and stores the same old value when there is no clock.

Answer

The derivative of e^(x) is e^(x) only

So the derivative of y=e^(ax+b)  wrt x will be e^(ax+b)*(derivative of (ax+b))

Reason: In place of x we have ax+b. So we have to differentiate ax+b as well

So. Derivative of (ax+b) =a.(1)+0=a

So final answer: dy/dx = e^(ax+b)*a

Hope it helps

Answer

A multiplexer is a logical circuit which has many inputs and only one output. It has control lines , to select always one of the inputs  and this goes to the output. 

Application:When you want to send only one signal from many using the control lines, MUX is used

One of the most commonly used in digital design.

Answer

In general there are 4 types of filters.

1. Low pass 2.High pass 3.Band Pass 4.Band Reject/Notch filter

But each of these filters can be active/passive filters

Answer

The secondary memory of a computer is non-volatile memory. Which means data once written to this memory is not lost, even though it is powered off. One such example is our Hard Disks, Pendrives etc

Answer

We have decimal number system in which we can represent any number using digits from 0 to 9.

Likewise , we have a binary number system , in which every number , whether positive or negative, howso ever large or small it may be , it is represented using only two digits 0 &1. Interesting isn't it?

Our computer understands everything only in binary format.

 

Answer

WAN stands for Wide Area Network. As the name suggets , the network spans across a large geographical area may be an entire campus.

whereas LAN(Local Area Network) stands for very small area. May be a room, or some part of the campus.
