digital signal just have level 1 or zero . but in the real life digital signal are not produced directly.just think when electricity generates what happens ? we gate a sinusoidal wave which have different-2 amplitude on different time.My mean there are no fixed level 0,1. Think when wheel of vehicle are moving they also generate analog signal.We can convert an analog signal to digital signal by using ADC(analog to digital converter).

What are basic elements of digital signal processing?
The basic elements in digital signal processing are an analog to digital converter, digital signal processor, and digital to analog converter. This process can take an analog input signal, convert it to digital for processing and offer an analog output.
Why is an anolog signal different then a didgital signal?
An analog signal is continuous and can take on an infinite number of values within a given range, representing information in a way that closely resembles the original physical phenomenon, such as sound or light. In contrast, a digital signal is discrete, consisting of binary values (0s and 1s), which represent information in a more structured and quantized manner. This difference allows digital signals to be more resilient to noise and interference, making them easier to process and transmit over long distances with higher fidelity.

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.
How do you convert digital signal to analogue signal?
There are several devices called digital to analog converters for this purpose. 1s and 0s of the digital signal are used to represent the digital signal in analog form.
What is encoding technique?
There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal
Why doesn't a digital TV with a digital tuner get a digital picture?
The signal sent to the TV must be a digital signal as well.
