PowerPoint Presentation on Frequency Measurement

In my previous post we have discussed about what is frequency and very basic things regarding to frequency.now we will go one step ahead.Here is a PowerPoint presentation to understand that how frequency can be measure.   To measure frequency we have to count no. of repeating event per unit time.that repetition may be thousand or may be in terms of lac or more than that. so to count it different methods are that.that is discussed in my presentation. read it carefully.

Trigonometry functions

→"Sine" function :-           - If function f is f:R -> C , f(a)=p(a) =p(x,y) and h(p(x,y)) = y . so that hof:R →R is called             sine function and is also known as "sin".           - Region :- [-1,1]           - Set of zero :- {kπ / k∈Z}

Voltage

In simple word,we can say that                                      Voltage=(no. of electrons at starting of )  - (no. of electrons at ending of )                                                          terminal                                          terminal >  voltage means electric potential energy per unit charge.unit of voltage is       joule per coulomb.  in any terminal if we enter suppose 2000 electrons but due to resistance in path at the end     of terminal if we get 1500 electrons than the difference of that electrons is denoted by  potential difference more simply voltage.

Frequency

What is frequency? → In simple word frequency means number of event  repeating  occurs per unit time. Let us take one example so that you can understand more clearly. → Unit of Frequency is Hertz. if frequency is high than unit will be Kilohertz(KHz) or Megahertz(MHz).       →Relation between frequency and Time Period is in inverse proportion. F=1/T.
