Examination of analog modulation types

If the signal to be transmitted in nature is beyond the perception of the target organism's sense organs (in terms of distance), then it can be transmitted electronically. It must either be recorded on a magnetic medium and delivered to the target organism, or it must be transmitted via electromagnetic waves or cable. If wireless communication is to be used here, then the signal must be modulated. The mpl modulation is used in electronics in two ways: analog and digital. In this thesis study, analog modulation types were examined. Theoretical information on the subject is given. These; definition of modulation types, areas where they are used, etc. Then, sample codes and graphics prepared in MATLAB for all 3 types of analog modulation ( mplitüde, frequency and phase modulation) were added to the thesis. In today's electronics, modulation is performed by keeping the transmitted and carrier signal in the same environment. However, each 2 signs can be found in different environments. In this case, the carrier can be transmitted to the environment where the signal to be carried is located and the modulation process can be performed in that environment. Receiver and transmitter circuits using these modulation types were examined (with ready-made circuit diagrams). Apart from the current standard electrical quantities ( mplitüde, frequency and phase), if other electrical quantities can be discovered or a suitable signal can be produced, then many different types of modulation may be possible for both analog and digital communication. As in the logic of random number generation, the transmitted and carrier signal can be transmitted not only with one type of modulation, but also with different types of modulation depending on the situation (for example, natural conditions, etc.). In other words, a transmitted signal can reach receivers with 3 different modulation types. In this case, the transmitted signal can be obtained in the relevant hardware according to the feature(s) of the receiver.
