F=1/T and T=1/F Frequency and period are inverse of each other

AMPLITUDE :The highest value of a signal is called amplitude.

FREQUENCY:Frequency of a signal can be defined as the total number of cycles completed in one second . It is measured in Hertz.

PHASE:A phase is the shift in the waveform w.r.t the time.It can be described as the shift in the signal along the time axis .It is measurd in radians and degree.

A composite signal can be decomposed into individual sine waves called harmonies.Fourier analsis is done to decompose a signal.the decomposed signals have different amplitude,frequency and phase.A periodic signal has …show more content…

The frequency domain plot of a voice signal is continuous because a voice is a non periodic signal.

The frequency domain plot of an alarm system is Discrete as it is a periodic signal.

a. 24 Hz b. 8 MHz c. 140 KHz
a) F=1/T
24=1/T
T=1/24*10^3=41.7 ms

b) F=1/T
8=1/T
T=1/8*10^6=0.125 microseconds

c) F=1/T
140=1/T
T=1/140*10^3=7.14 micro seconds

a) F=1/T =1/5=0.2 Hz
b) F=1/T=1/12*10^-6=3.33 KHz
c) F=1/T=1/220*10^-9=4.55 MHz

a. A sine wave with the maximum amplitude at time zero
