Course Notes - Purdue University College of Engineering
engineering.purdue.edudigital video. One can obtain discrete-time signals by sampling continuous-time signals (i.e., by selecting only the values of the continuous-time signal at certain intervals). Just as with signals, we can consider continuous-time systems and discrete-time systems. Examples of the former include atmospheric, physical, electrical
Adding Time on a Calculator - Pyramid Time Systems
www.pyramidtimesystems.comAdding time on a calculator without converting the minutes to hundredths is inaccurate. Units of time are calculated as 60 minutes equals 1 hour, but a calculator uses units of 100. For example, if an employee worked 9 hours and 30 minutes on one day and 8 hours and 45 minutes on the day, the time card would display 9:30 for day 1 and 8:45 for ...
Lecture 11: Discrete-time Fourier transform
ocw.mit.eduSignals and Systems 11-2 rather than the aperiodic convolution of the individual Fourier transforms. The modulation property for discrete-time signals and systems is also very useful in the context of communications. While many communications sys-tems have historically been continuous-time systems, an increasing number
Stability Condition of an LTI Discrete-Time System
web.njit.eduClassification of LTI Discrete-Time Systems • The output y[n] of an FIR LTI discrete-time system can be computed directly from the convolution sum as it is a finite sum of products • Examples of FIR LTI discrete-time systems are the moving-average system and the linear interpolators
