In the case of rectangular waves (often used in digital technology), the modulation process is subject to the width, amplitude, position (arrangement) and density of pulses. The frequency of changes caused by modulation is much lower than the wave frequency. An example is the modulated sound of a variable frequency alarm siren.
The modulation device is called the modulator. Demodulation (in other words: detection) is a process that is inverse to modulation. A device called a demodulator or detector reproduces a modulation signal from a modulated waveform.
If the communication has a two-sided character (eg full duplex), then one device modulates the transmitted signals simultaneously and demodulates those that it receives (modulator-demodulator, or in short a modem).
Modulation and modulators proposed by Thor Broadcast are necessary in virtually every AV set, especially in such, in which the computer is involved.
The signal used in them must be capable of transmission via the telecommunications network. Physical limitations cause information to be distorted due to noise, distortion and crosstalk from other signals sent in the same facility. Therefore, choosing a good Thor modulator is so important. The modulated message after overcoming all these obstacles must be so correct that the recipient can extract useful data from it.
