What is Sinusoidal Signal ?
Sinusoidal are the most smooth signals with no abrupt variation in their amplitude, the amplitude witnesses gradual change with time. Sinusoidal signals can be defined as a periodic signal with waveform as that of a sine wave. The amplitude of sine wave increase from a value of 0 at 0° angle to a maximum value of 1 at 90° , it further reaches its minimum value of -1 at 270° and then return to 0 at 360° . After any angle greater than 360° , the sinusoidal signal repeats the values so we can say that time period of sinusoidal signal is 2π i.e. 360°.
If we want to observe the variation in the amplitude of sinusoidal signal with varying angle, we can plot a graph as shown below.
sine wave
If we observe the graph, we can see that the amplitude varying gradually with a maximum value of 1 and a minimum value of -1. We can also observe that the wave begins to repeat its value after a time period or angle value of 2π hence periodicity of sinusoidal signal is 2π.
Sinusoidal Signal
Sinusoidal Signal is an important tool in the electronic industry. They are ubiquitous in modern electronics and are almost used in every daily appliance for input as Voltage, Current, and power amplifiers. In this article, we will study what a sinusoidal signal, how does it look like. We will also represent the Sinusoidal signal mathematically. Later we will discuss the need of having Sinusoidal signal and some applications of Sinusoidal Electronic Signal. We will conclude the article by summing up what we have learned. The electronics industry especially the communication system uses these signals in various circuits and readers can read about these other signals as well.
