What is Comparator

Comparator A comparator is a circuit that compares two input voltages or currents and gives output High or Low as per input signal. The Output is a digital form according to the input signal compared with the reference. Basically a comparator is used in electronics to compare the two Analog input signals given on both input terminals and we get […]

Operational amplifier (Op-amp)

Operational Amplifier (op-amp) An operational amplifier or op-amp is basically a multistage, very high gain amplifier having very high input impedance (typically a few Mega ohms) and low output impedance(Less than 100 ohms) and has the capability to amplifying signals of frequency ranging from zero HZ to 1MZ. Opamp is basically a multistage, direct-coupled, negative feedback amplifier that uses voltage […]

AC vs DC

difference between ac and dc AC vs DC AC DC 1 AC means alternating current DC means direct current 2 AC current reverses its direction periodically. AC alternates its direction within a circuit over time DC current flows in only one direction. DC does not change across time. 3 The magnitude of the current vary with time AC current […]
