Unit impulse function Unit step function Their relation in both continuous and discrete domain We shall even look at the Sifting property of the unit impulse function Basic Signals in detail We now introduce formally some of the basic signals namely In this lecture we discuss these signals and then proceed to a discussion of sys tems first in general and then in terms of various classes of systems defined by specific system properties The unit step both for continuous and discrete time is zero 7.5 The student will read and demonstrate comprehension of a variety of fictional texts, narrative nonfiction, and poetry. .. e) Make. , confirm, and revise predictions. . What is a prediction? . A prediction is a forecast or an educated guess of what may happen next. Examples of signals:. Voltage output of a RLC circuit, stock market, ECG, speech, sequences of bases in a gene, MRI or CT scan. Examples of systems:.
