can represent an infinite number of valuesĢ. Compared to analog systems, digital systemsī. Having two values or states describes a number system that has a base of two and utilizes 1 and 0 as its digits.Ī basic timing signal in a digital system a periodic waveform used to synchronize actions.Ī logic circuit that performs a basic logic operations such as AND or OR.Ī basic logic function that performs inversion.Ī category of digital integrated circuits having functions that cannot be altered.ġ. Related to digits or discrete quantities having a set of discrete values. In general, they cost less and use less board space that fixed function devices.īeing continuous or having continuous values. The logic can be programmed for a specific purpose. Programmable logic devices (PLDs) are an alternative to fixed function devices. In this case, testing can be done by a computer connected to the system.įor measuring digital signals, use DC coupling The circuit is wired using DIP chips and tested. Sequence of binary codes that represent the number of input pulses counted.Ĭutaway view of DIP (Dual-In-line Pins) chip:Īn example of laboratory prototyping is shown. True only if one or more input conditions are true.Īnd, or, and not elements can be combined to form various logic functions.

Duty cycle is the ratio of tW to T.Ī timing diagram is used to show the relationship between two or more digital waveforms,ĭata can be transmitted by either serial transfer or parallel transfer. In addition to frequency and period, repetitive pulse waveforms are described by the amplitude (A), pulse width (tW) and duty cycle. What is the period of a repetitive wave if f = 3.2 GHz? The clock is a basic timing signal that is an example of a periodic wave. The frequency is the rate it repeats and is measured in hertz. Periodic pulse waveforms are composed of pulses that repeats in a fixed interval called the period.

Digital waveforms are made up of a series of pulses.Īctual pulses are not ideal but are described by the rise time, fall time, amplitude, and other characteristics. A positive going pulse is one that goes from a normally LOW logic level to a HIGH level and then back again. A bit can have the value of either a 0 or a 1, depending on if the voltage is HIGH or LOW.ĭigital waveforms change between the LOW and HIGH levels. In binary, a single number is called a bit (for binary digit). The voltages represent numbers in the binary system. A typical CD player accepts digital data from the CD drive and converts it to an analog signal for amplification.ĭigital electronics uses circuits that have two states, which are represented by two different voltage levels called HIGH and LOW. Many systems use a mix of analog and digital electronics to take advantage of each technology. Analog systems can generally handle higher power than digital systems.ĭigital systems can process, store, and transmit data more efficiently but can only assign discrete values to each point. Most natural quantities that we see are analog and vary continuously. © 2009 Pearson Education, Upper Saddle River, NJ 07458. Slide 1© 2009 Pearson Education, Upper Saddle River, NJ 07458.
