Diqital system entity can process, transfer and store any kind of diqital signals is Composed of individual digital logic circuits which are designed to erform specified function
Digital system: • entity • can process, transfer and store any kind of digital signals • is Composed of individual digital logic circuits which are designed to perform specified function
physical signal (transformation rule) Digital signal: discrete quantities Analog signal: continuous quantities PAM The difference between analog and digital lies in the method of Encoding information
