Should be a sine ( or cosine) wave.
The set top box that your provider gives you is what converts the Digital signal to the analog signal. The digital signal is compressed at the provider and sent to the end user. The "tuner" (which can be built into a tv, a set top box or a cable card) Then decompresses the digital signal and converts it into an analog signal. There is much more to this did not know how technical you wanted your answer.
The parameters of analog signals are 1.Amplitude 2.Wavelegth 3.frequency 4.phase angle
Set top box is basically used to convert the digital signals broadcasted by digital signal broadcasters to analog signals, in case you wish to have your analog tv, but would like to have an access to digital channels. Digital channels definitely have better quality signals than analog and therefore you will have a better picture quality and signal quality even though you have converted the digital signals to analog.
the digital code is binar. so if you get a signal it is absolut. analogue signals can be interfered or altered through interferation.
No.
Analog
A digital audio jack serves the same purpose as an analog audio jack, only it transmits a signal that is digital (1s and 0s) instead of analog (waveform).
A: ANALOGUE IT can be AC or DC it is up to the application involved An analog signal can be a sine wave, a square wave a sawtooth wave or any other varying waveform
Analog Modulation
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.
When you convert digital signal to analog, it is called as an analog signal. The device used is called digital to analog converter.
Draw thewaveform of AM signal and DSBSV
Digital signal processing is the best compared to analog signal. It is because the digital signal is moreefficienterror freeimmune to noisethan an analog signal
An analog signal is simply a quantity varying continuously over time..But because we are interested in information and communication, we are usually interested in rapidly varying signals that have some underlying periodicity. Therefore we use sin wave
There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal
They both convey differences in voltage level. An anologue signal can send any level between limits. A digital signal only sends two different levels, one represents a 1 or high level, the other represents 0 or low level.
A video uses the analog signal
