A scanner creates an analog representation of a printed digital image?
Are you kidding me?! Read your book.
Is PCM is an example of analog to digital?
No, Pulse Code Modulation is a communication method used to carry digital data but is not part of any analog to digital conversion. PCM is often used to carry audio data as a digital stream and therefore is the encoding used as the signal is first converted to a digital format.
What is quantization error?
Error resulting from trying to represent a continuous analog signal with discrete, stepped digital data. The problem arises when the analog value being sampled falls between two digital "steps." When this happens, the analog value must be represented by the nearest digital value, resulting in a very slight error. In other words, the difference between the continuous analog waveform, and the stair-stepped digital representation is quantization error.
Can you turn your analog police scanner digital with a converter box?
No, a television converter box will not work on a police radio scanner. There is currently no way to make this conversion. One cost-effective method of listening to digital police, fire and other communications without purchasing a digital police scanner is through the download and installation of a free smartphone application which receives digital transmissions. There are many available for both Android and iPhone.
Difference between analog representation and digital representation?
An analog representation displays information in a continuous way, for example... the presentation of a wall clock shows the time in as a continuous variable, taking on any value within its constituent resolution. digital representation, also called discrete representation, displays information in terms of discrete, symbolic values, normally in terms of codes. In keeping with the same example, a digital representation would be a digital clock, whose representation of time is in terms of discrete variables (numbers)
How do you pick up digital snignal on analog scanner?
To pick up digital signals on an analog scanner, you can use a technique called "digital decoding." This involves connecting the scanner to a digital signal decoder or a computer with appropriate software that can interpret the digital signal formats, such as P25 or DMR. Additionally, using a discriminator output can help extract the audio from the digital signal, allowing you to listen to the transmission. However, keep in mind that not all digital signals can be decoded this way, and some may require specific equipment or software.
The difference between Digital signal and analog signal?
I'm not sure if you are speaking of a specific instance.... However, a digital signal is a binary representation of the analog signal. The analog signal is constantly measured and the amplitude (voltage at the time of sample) of the analog signal is converted to a binary number at specific intervals (the frequency of the sample rate). The higher the frequency of the sample rate, the more accurate the representation of the analog signal.
If you get an aircraft scanner antenna do you need to get anything else to listen to it like speakers?
no as long as you have a scanner to hook up the antenna to analog scanner there about 100 dollars digital ones are 400 the scanners have the speaker on them
What converts a message from digital to analog and analog to digital?
An DAC convert digital signal to analog signal i.e Digital to Analog Converter. An ADC convert analog signal to digital signal i.e Analog to Digital Converter.
Does a digital camera use digital signals?
The signal directly from the sensor is analog. It is than converted to digital, and a digital signal is used for processing. The signal directly from the sensor is analog. It is than converted to digital, and a digital signal is used for processing.
When was the digital police scanner first invented?
The first digital police scanner was invented in the 1970's. Unlike earlier analog version (which were basically AM Radios, as police just used to broadcast using regular radio waves), this scanner was the first to allow you to punch in a frequency to search for the police frequency.
What hardware is needed to convert the digital signal of the computer to signals that can be transmitted through telephone lines?
