example of analog modulation
Analog modulation techniques offer several benefits, including simplicity in implementation and ease of understanding, making them suitable for various applications. They typically require less complex equipment than digital modulation, which can result in lower costs for transmission systems. Additionally, analog modulation can provide better performance in terms of signal quality over short distances and is effective for continuous signals, such as audio. However, it is generally more susceptible to noise and interference compared to digital modulation.
AM stands for Amplitude Modulation, which is a method used to encode information onto a radio wave by varying the strength (amplitude) of the wave. In terms of wavelength, AM refers to the distance between two consecutive crests or troughs of a wave.

In terms of the history of the signal, it was the analog signal that came first. That doesn't mean that it can't still be used in conjunction with an analog signal in today's use.
Amplitude Modulation Double Sideband Full Carrier (AM DSB FC) is primarily used in analog broadcasting, such as AM radio stations, where it transmits audio signals over long distances. Additionally, it finds applications in two-way radio communications, aviation communication systems, and in some television broadcasts. Due to its simplicity and ease of demodulation, AM DSB FC is also used in various telemetry and remote sensing applications. However, it is less efficient in terms of bandwidth and power compared to modern modulation techniques.
An analog representation displays information in a continuous way, for example... the presentation of a wall clock shows the time in as a continuous variable, taking on any value within its constituent resolution. digital representation, also called discrete representation, displays information in terms of discrete, symbolic values, normally in terms of codes. In keeping with the same example, a digital representation would be a digital clock, whose representation of time is in terms of discrete variables (numbers)
There are two basic kinds of computers: analog and digital. An analog computer represents information in terms of some physical parameter (e.g., the distance a gear has traveled), whereas a digital computer represents information in terms of a code composed of discrete states (i.e., "on" or "off"). When numerical values are represented in these ways, an analog computer's physical state corresponds to a point on the real number line, while a digital computer's digits are sharply distinct from one to the next.

venus (in terms of distance from the sun). In terms of distance from the earth, it is Mars In terms of size, it is Saturn.
distance measured not in linear terms such as miles or kilometers but in terms such as cost and time
example of definition of terms
A location is the position which is usually measure in terms of a fixed point of reference, which is called the origin. In n-dimensional space the location may be defined in terms of distances from origin along orthogonal axes (n axes), or in terms of distance and direction (one measure of distance and n-1 angles). Location on the surface of a sphere, for example the earth, can be defined by only two angles (the latitude and longitude) and no distance because the distance is implied (radius of the earth).
