Modulators are used in telecommunications to send information. In order to transmit information from the transmitter to the receiver, the carrier wave (high frequency signal in a given band) must be modulated with information (e.g. voice, data, low frequency modulation signal, ) with a different frequency. Depending on the type of modulation, the modulator must change the appropriate information size in a given cycle.
Example from practice: An FM radio station (e.g. 100 MHz) generates a carrier wave with an average frequency of 100 MHz, but changes (modulates) its frequency in time using a low frequency signal (voice, music). This can be done, for example, by means of a capacitive diode in the resonant circuit of a high-frequency oscillator to which a low-frequency signal is applied. In this way, its capacity in the LF signal cycle, and thus the resonance frequency of the resonant circuit, changes.
HDMI digital modulator works exactly as described above, using a digital signal which is practically used in all popular applications, instead of an analog signal. The HDMI connectors themselves are a modern and practical solution applied in most of the modulators nowadays.
