Question

Difference between analog pulse modulation and digital pulse modulation

Answer 1

1.Analog modulation takes an analog signal while digital modulation takes a digital signal.
2.Analog modulation has a range of valid values while digital modulation only has two.
3.Analog modulation is cheaper to implement than digital modulation.
4.Digital modulation produces more accurate output than analog modulation.

Answer 2

Answer:

Signal Analog signal is a continuous signal which represents physical measurements. Digital signals are discrete time signals generated by digital modulation. Example Human voice in air, analog electronic devices. Computers, CDs, DVDs, and other digital electronic devices.

Analog modulation is typically used for AM, FM radio, and short-wave broadcasting. Digital modulation involves transmission of binary signals (0 and 1). Digital modulation involves transmission of binary signals (0 and 1).

Explanation:

Analog Modulation: The wave in continuous modulation when the time difference in the variable is specified is determined by analogue modulation. Low-frequency signals can be sent with its assistance. It additionally accepts audio signals with high-frequency carrier signals. There are three different kinds of it, and each has particular characteristics. The values are regarded as valid if they fall within the defined range.

Digital Modulation: High security will be provided by digital modulation, and the information can be transmitted swiftly using this technique. They are in more demand since they have a good capacity to transfer big volumes of data across analogue medium. We can select the sort of modulation from the three options supplied based on the kinds of combinations we want to employ for our task.
