Why we need to modulate an analog signal it is already analog?
One may ask why we need to modulate an analog signal; it is already analog. Modulation Modulation is needed if the medium is bandpass in nature or if only a bandpass channel is available available to us.
Why is digital modulation preferred over analogue modulation?
Information capacity, data security, communication quality, and system availability are properties of digital modulation that make it more advantageous than analog modulation.
What is analog to digital modulation?
Analog-to-digital conversion (ADC) is an electronic process in which a continuously variable, or analog, signal is changed into a multilevel digital signal without altering its essential content.
Why is digital transmission superior to analog?
Digital signals can convey information with less noise, distortion, and interference. Digital circuits can be reproduced easily in mass quantities at comparatively low costs. Digital signal processing is more flexible because DSP operations can be altered using digitally programmable systems.
