Mode 1 ( 0
By applying a positive output pulse of the pulse width modulator to the transistor Q1 it gets turned on. An input current in flows through Vin Q1 inductor L and then divides into two parts one flows through capacitor C and other through load.
In this mode inductance stores the energy and induced voltage in inductor bunks the input voltage.
Q. Sketch the timing diagram for a 4-bit ripple counter which uses T flip-flops.
To convert a galvanometer to a voltmeter, you should add a: a) High resistance in series b) High resistance in parallel c) Low resistance in series d) Low resis

Q. What do you mean by Superposition and linearity? Mathematically a function is said to be linear if it satisfies two properties: homogeneity (proportionality or scaling) and
Q. Explain Source encoding or data compression? The sequence of binary digits from the source encoder, known as the information sequence, is passed on to the channel encoder. T
Earthing : Any electrical appliance with a metal casing or with metal parts, likely to be touched by an operator is potentially dangerous. The danger is that an internal or extern
Define the XOR GATE - Microprocessor? The XOR GATE is a alike to an OR gate except for the instance when all the inputs are high. With a XOR gate when all the inputs are high t
For large number of measurements the mean is calculated by taking a sample. Each sample that is taken has a mean. The mean of various sample difference from sample and are known to
