A signal that only takes discrete values (contrasted to an analog signal that can take continuously varying values).
The red digital signal is the sampled and quantized representation of the gray analog signal. A digital signal consists of a sequence of samples, which in this case are integers: 4, 5, 4, 3, 4, 6...
A signal that only takes discrete values (contrasted to an analog signal that can take continuously varying values).
A binary signal, also known as a logic signal, is a digital signal with two distinguishable levels
A signal that only takes discrete values (contrasted to an analog signal that can take continuously varying values).
Discrete cosine waveform with a frequency of 50 Hz and a sampling rate of 1000 samples/sec, efficiently satisfying the sampling theorem for the reconstruction of the original cosine function from samples. (The effects of quantization are too subtle to be seen in this graph.)
