pulse code modulation method used a telephony.
the modulation system is of FM
because of wadda
Analog
PCM (Pulse Code Modulation)
frequency modulation..
"Base band", meaning that no modulation is used."Base band", meaning that no modulation is used."Base band", meaning that no modulation is used."Base band", meaning that no modulation is used.
telegraphy.
I think it is Frequency Modulation with Phase modulation which it the most bandwidth efficient
Adaptive delta modulation is used in audio communication systems to avoid the two drawback of delta modulation.
the highest modulation coefficient is one (1) and percent modulation is 100
Adaptive delta modulation is used in audio communication systems to avoid the two drawback of delta modulation.
Samuel Morse is credited with perfecting the electrical telegraphy system in the 1830s, including the development of the Morse code. His work revolutionized long-distance communication.
