What do you mean by L,C,R circuit?
Vikas | 1 day ago
An inductor (L), and a capacitor (C), a resistor (R), connected in series or in parallel make electrical circuit. The name of the circuit is derived from the letters that are used to denote the constituent components of this circuit.
What do you mean by discrete - time function?
Pratik | 1 day ago
Discontinuous time. For example a doctor measure temperature of a patient after an interval of 5 hours. So doctor will have patient's temperature at interval of 5 hours. So temperature is a discrete time function.
Define polar plot?
Sanjeev S S | 2 days ago
A plot of radial distance versus the angle it makes with the x-axis is called polar plot.
Vikas | 1 day ago
Polar Plot. A plot of a function expressed in polar coordinates, with radius as a function of angle. As we have Cartesian Plot X,Y Graph, similarly R,Theta Coordinates i.e. Radius & Angle coordinates gives Polar Plot. To convert from Polar Coordinates (r,theta) to Cartesian Coordinates (x,y) : x = r × cos( theta ) y = r × sin(theta )

A metal-oxide-semiconductor field-effect transistor (MOSFET) is a voltage-controlled electronic component invented by a South Korean Engineer Dawon Kahng, and his colleague Martin M. Atalla in 1959 whilst working at Bell Labs. It was the first insulated gate FET, consisting of a metal gate (M), oxide insulation (O), and silicone semiconductor material (S). In this device, a voltage at the gate junction produces an electric field, which controls the current flowing between the source and drain junctions. This MOS technology was later utilised to develop integrated circuits (IC) which Kahng foresaw. The differences in the operation between a MOSFET and a bipolar junction transistor (BJT) are huge, but the main ones are that a BJT is a current controlled device because current at the base junction controls the flow of current between the collector and emitter junctions. However, a MOSFET is a voltage-controlled device, where a voltage at the gate junction creates an electric field, which controls the flow of current between the source and drain junctions.
