What is modulation (FSK, ASK, pulse)?
Answer
FSK (Frequency Shift Keying) modulation is a modulation method in which the information (analog signal) you want to send is frequency-modulated and transmitted. ASK(Amplitude Shift Keying) modulation is a modulation method that transmits the information (analog signal) to be transmitted by using the strength of the carrier in the amplitude direction. The pulse-width modulation is a modulation method performed by changing the amplitude, width, phase, etc. of the pulse.
