What is modulating a signal?
Modulation is defined as the process of superimposing a low-frequency signal on a high-frequency carrier signal. Or. The process of varying the RF carrier wave in accordance with the information in a low-frequency signal.
Which signal is modulating signal?
Frequency modulation (FM)
Because the frequency of a radio wave is less vulnerable to noise than the amplitude, FM was originally introduced to reduce noise and improve the quality of radio reception. In order to accomplish this, FM radio signals have bandwidth several times that of AM signals.
What is modulating signal in FM?
As we know, a modulating signal is nothing but information or message that has to be transmitted after being converted into an electronic signal. Much like amplitude modulation, frequency modulation also has a similar approach where a carrier signal is modulated by the input signal.
What is modulation signal and its types?
Modulation is the process of converting data into electrical signals optimized for transmission. Modulation techniques are roughly divided into four types: Analog modulation, Digital modulation, Pulse modulation , and Spread spectrum method.
