Time t is continuous, and most physical phenomena output continuous signal values. 3 System with its input and output in the frequency domain. 14 Digital Clocks for Synchronization and Communications spontaneous but instead represent the desire to sample a continuous signal at regular intervals. Such a system is often called a logic circuit or a digital system. The input signal and the output signal are generally expressed as series of binary (0 and 1) bits. For example, (0110111) is a 7-bit binary number and equals 55 in the common decimal notation.

9(a). Phase comparison results appear continuously at the output. The output frequency and phase show smooth and continuous changes since the controlled oscillator is continuously steered by the analog signal from the comparator. A 36 Digital Clocks for Synchronization and Communications practical realization can be based on a double balanced RF mixer and a suitable voltage controlled oscillator (VCO). The main feature of the analog PLL is its excellent control precision. 9(b)]. It appears to be a kind of digital PLL.

For some time the Laplace transform and operational calculus were said to be identical even though no strict mathematical proofs had been provided. Such proofs have now been provided by Mikusinski [4] and Schwartz [5] in different ways. 7. However, this is a simple rewriting action of variable ω (a real number) to variable s (a complex number). The meaning of this is explained later in this section. 7 Laplace transform expression for a system. 4) under some assumptions such as linearity. 4) The reader is encouraged to consult [2] or [6] for details of such assumptions and for a more complete description.
