Twisting the cables is done to remove the electromagnetic interference from the wires. When a signal is transmitted through the cable it is in the form of current. This flow of current produces an electromagnetic field of interference around it and can generate noise effects...

Enhancement Mode MOSFET: For an enhancement MOSFET, the channel does not initially exist. It only comes into existence once a voltage greater than Vth, threshold voltage is applied. For example, in an n-channel MOSFET, the substrate is made of p-type material. Consider the source to...

Triggering basically means switching. The way in which a switch or an event is triggered can be different, based on the user’s requirements. Edge and Level Triggering, are both common terms when using sequential circuits like Flip Flops triggered by a clock signal. Essentially, this...
