Answer 1:
There is two type of electromagnetic signal: Analog signal and Digital Signal. We can differentiate both the signal because of flowing reasons.
Analog signal is a signal which is continuous and vary in time and it followed the non electric signal variation that means the representation of analog signal is sine wave where as the electrical signal which is non continuous and change in step and followed the digits and pulses is known as digital, it means square wave represented the digital signal.
Answer2:
The three important charterstics of a periodic signal are: Amplitude, Frequency and Phase.
Amplitude: it the signal’s instantaneous value measures at any time in volt.
Frequency: it is number of inverse of period and expressed in hertz (Hz) or cycles per second.
Phase: it measured the relative position of signal in time within signal’s single period.
Answer 3:
If we see the complete circle of 360 degree then finds that there is 2π radian in the circle of 360 degree.
So 2π radians = 360 degree
Answer 4:
The frequency and wavelength of light are elated to each other closely. The relationship between frequency and wavelength of sign wav is represented by an equation: λf= v
Where λ is wavelength, f s frequency and v is signal speed at which it is travelling.
Answer 5:
The rage of frequencies which contained in the signal is defined as a spectrum of signal where as the difference between the highest and lowest frequency in the spectrum is known as bandwidth of signal. In other words, the signal of the bandwidth is the spectrum bandwidth.
