Market orders are to be executed as soon as possible after reaching the exchange floor. Limit orders must specify a price and a time limit, e.g. \Buy 500 at $90, good till canceled.\ A stop order differs from a limit order in that the order is only executed if the specified price, called the stop price, is touched. Stop orders become market orders when the stop price is reached

Bond Principles: Identification- of Bonds Bonds are identified by issuer, coupon rate, and maturity. The face value of a bond is called its par value. e.g. 5 of \Hertz sevens of 03\(Hertz 7s03) .A legal document called the indenture contains the details of the bond issue

SAMPLING We live in a continuous-time world most of the signals we encounter are CT signals, e.g. x(). How do we convert them into Dt signals x[n? Sampling, taking snap shots of x(t) every Seconds

Motivation for the Laplace transform CT Fourier transform enables us to do a lot of things, e. g Analyze frequency response of lTi systems Sampling Modulation Why do we need yet another transform? One view of Laplace Transform is as an extension of the Fourier
