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.
