Problems of Type P(A) = n(A)/n(S)
Subject and UNIT: Random Process and Linear Algebra: Unit I: Probability and Random Variables,,
If we assume that all outcomes of an experiment are equally likely to occur, then the probability of any event E equals the proportion of outcomes in the sample space that are contained in E. P (E) = number of points in E / number of points in S
Theorems of Axioms Probability
Subject and UNIT: Random Process and Linear Algebra: Unit I: Probability and Random Variables,,
The probability of an event has been defined, we can collect the assumptions that we have made concerning probabilities into a set of axioms that the probabilities in any random experiment must satisfy. The axioms do not determine probabilities; the probabilities are assigned based on our knowledge of the system under study. However, the axioms enable us to easily calculate the probabilities of some events from knowledge of the probabilities of other events.

Buck converter is also known as step down converter and produces a lower output voltage than input voltage. The average output voltage is less than the input voltage.
Operation, Switching-Mode Regulator
Subject and UNIT: Electronic Devices and Circuits: Unit V: Power Amplifiers and DC/DC Converters
The DC to DC converters convert one level of DC voltage to another level. It is also known as DC chopper. Different electronic devices require different operating voltages. Ex: ICs, MOSFET Also in industrial applications, a fixed voltage de source needs to be converted into a variable voltage de source. DC choppers are used to provide different voltage for each device. It can be used to step-up or step-down a dc voltage source.
