| | As a result, the values of such a signal are restricted to belong to a finite set; in other words, it is quantized. | | | The two main types of signals are analog and digital. | | | In short, the difference between them is that digital signals are discrete and quantized, as defined below, while analog signals possess neither property. |

| | Digital signal processors have heavily parallel architectures optimized for DSP computations and are designed to operate in real-time. | | | The output of an FIR filter to any given input may be calculated by convolving the input signal with the impulse response. | | | The mathematical calculations and algorithms required for DSP are sometimes executed in hardware digital signal processors, also abbreviated DSP. |

| | An easy example of a digital signal is a binary sequence, where the values of the function can only be one or zero. | | | Along with the classification of signals below, it is also important to understand the Classification of Systems. | | | On the other hand, a random signal has a lot of uncertainty about its behavior. |
