which of these is true about the differences between analog and digital media?

In analog technology, a wave is recorded or used in its original form. So, for example, in an analog tape recorder, a signal is taken straight from the microphone and laid onto tape. ... In digital technology, the analog wave is sampled at some interval, and then turned into numbers that are stored in the digital device.

An analog signal is a continuous signal that represents physical measurements. Digital signals are time separated signals which are generated using digital modulation. It uses a continuous range of values that help you to represent information. Digital signal uses discrete 0 and 1 to represent information.

Digital signals must have a finite set of possible values. The number of values in the set can be anywhere between two and a-very-large-number-that's-not-infinity. ... That's the big difference between analog and digital waves. Analog waves are smooth and continuous, digital waves are stepping, square, and discrete.

Difference between DO and AO A digital output is binary in nature, either it can be ON or it can be OFF. Either it can be 0V or it can be 24V based on the type of IO module used. Analog signal is a time-varying signal. It can be varying between 0-10V or 0-20mA based on the design.

Both analog and digital modulation use smoothly varying signals; the difference is that an analog-modulated signal is demodulated into an analog baseband waveform, whereas a digitally modulated signal consists of discrete modulation units, called symbols, that are interpreted as digital data.

Analog and digital signals are used to transmit information, usually through electric signals. In both these technologies, the information, such as any audio or video, is transformed into electric signals.

As a technology, analog is the process of taking an audio or video signal (in most cases, the human voice) and translating it into electronic pulses. Digital on the other hand is breaking the signal into a binary format where the audio or video data is represented by a series of "1"s and "0"s.

A standard analog radio is going to decrease in signal the closer you get towards its maximum range, at which point all you hear is white noise. On the other hand, a digital radio is going to remain much more consistent in sound quality regardless of distance to or from the maximum range.

The basic difference between analog and digital computers is the type of data they process. ... Digital computer process data which is binary, i.e. in the form of 0 and 1. Analog computers operate on mathematical variables in the form of physical quantities that are continuously varying.

Digital signals can be generated through AC or DC circuits of varying voltages, resistances, or amperages. Analog signals on the other hand convey information on a range. While there may still be 0's and 1's now there are values in-between as well (e.g. 0.1, 0.32, 0.76, etc.).

Most commonly digital signals will be one of two values -- like either 0V or 5V. Timing graphs of these signals look like square waves. That's the big difference between analog and digital waves. Analog waves are smooth and continuous, digital waves are stepping, square, and discrete.

Digital Signals. Digital signals must have a finite set of possible values. ... That's the big difference between analog and digital waves. Analog waves are smooth and continuous, digital waves are stepping, square, and discrete.

Difference between Analog and Digital Computer. The analogue computer works on a continuous signal. The digital computer works on a discrete signal. ... The output is a voltage signal, they are not exact values and are in graphical form.

Analog is a method of transmitting information by a continuous but varying signal. ... Digital is a method of storing or transmitting information by discrete, non-continuous impulses.

Digital is a format of video distribution, the alternate being electromagnetic waves of 20th century yore. HD (High definition), meanwhile, is a video resolution. That quite literally means the amount of pixels on the display. The more the better, but screen size any type can also prove a limitation when going HD.

At a practical level, the difference between analog and digital is in how the information/data is measured. Analog data attempts to be continuous and identify every nuance of what is being measured, while digital data uses sampling to encode what is being measured.

The security of an analog signal is not encrypted, whereas a digital signal is encrypted. The analog signal bandwidth is low, whereas the digital signal is high. The data storage of an analog signal is in the wave signal form, whereas digital signal stores the data in the binary bit form.
