Pulse width (tW) Amplitude (A) Period, TĪ timing diagram is used to show the relationship between two or more digital waveforms, A diagram like this can be observed directly on a logic analyzer.ĭata can be transmitted by either serial transfer or parallel transfer.ġ1 Summary AND OR NOT Basic Logic Functions In addition to frequency and period, repetitive pulse waveforms are described by the amplitude (A), pulse width (tW) and duty cycle. Example What is the period of a repetitive wave if f = 3.2 GHz? Solution 313 ps 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.ħ Summary Example Solution Periodic Pulse Waveforms A positive going pulse is one that goes from a normally LOW logic level to a HIGH level and then back again. HIGH VH(min) Invalid VL(max) LOW VL(min)ĭigital waveforms change between the LOW and HIGH levels. A bit can have the value of either a 0 or a 1, depending on if the voltage is HIGH or LOW. VH(max) 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. Digital systems can process, store, and transmit data more efficiently but can only assign discrete values to each point.

Analog systems can generally handle higher power than digital systems. Most natural quantities that we see are analog and vary continuously. 1 Digital Fundamentals Floyd Chapter 1 Tenth Edition
