Calculate v(t) for different values of t. Plot the values for v(t) on the vertical axis for values of t on the horizontal axis.esmeco said:I was wondering,how do I represent graphically an analog signal components in time and frequency using an equation for example like this:
v(t)=3 + 1.414cos(w0t) - 1.414sin (w0t) + 2cos(2w0t + 5pi/2)
Thanks in advance for the reply!
An analog signal is a continuous electrical signal that represents information in the form of varying voltage or current levels. It is often used to represent audio, video, and other types of data.
An analog signal is typically represented graphically using a waveform, where the amplitude (height) of the waveform corresponds to the voltage or current level at a particular point in time. The horizontal axis represents time and the vertical axis represents voltage or current.
Some common tools used to represent analog signals graphically include oscilloscopes, function generators, and data acquisition systems. These tools allow for precise measurements and visualization of the analog signal.
An analog signal is continuous and can take on an infinite number of values, while a digital signal is discrete and can only take on a finite number of values. In other words, an analog signal can have any value within a certain range, while a digital signal can only have specific values (e.g. 0 or 1).
Graphical representation of analog signals is useful for analyzing and understanding the characteristics of the signal, as well as for troubleshooting and making adjustments to the signal. It can also be used to compare signals and identify patterns or anomalies.
