CISM courses [2]. It deals with the problem of identifying a model describing some physical system by measuring the response of the system. This is don e by designing the input signal‚ which is applied to the system [3]‚ whereas output is taken as impulse response of system. Input signal is used for excitation. In this paper identification has been achieved by basic approaches as variable frequency signa l (chirp)‚ coherence function and pseudo inverse. II. SYSTEM IDENTIFICATION A suitable

points] Consider a linear time-invariant (LTI) system with impulse response h(t) whose Fourier transform is H(f ) = ∧(f ). Recall that ∧(f ) is non-zero only from f = −1 to f = +1. Find the output of the system if the input is: (a) x(t) = sin 0.5πt Solution: ∧(0.25) sin 0.5πt = 0.75 sin 0.5πt (b) x(t) = cos 10πt Solution: ∧(5) cos 10πt = 0 Question 2: [6 points] An input signal x(t) = sinc (4t) is applied to to an LTI system with impulse response h(t) = sinc (6t). Let the output of the LTI system

Beauty and the Creative Impulse This essay‚ out of the three‚ was my favorite. The author had a lot of good points to support her thesis in which she stated that beauty is something integral of the world we live in; the earth that the Creator created. She also brought up the fact that sometimes we move so fast that we take beauty for granted. In this day and age‚ we live our lives in fast forward and we‚ almost literally‚ do not even attempt to stop or even slow down to smell the roses. She

SHAMINMENISHA How Water Rockets Work A water rocket works using the same principles as other rockets. There are three main forces in action: thrust (Fapp)‚ drag (Ffr) and weight (w=mg). The water‚ which is forced out by the difference between internal and atmospheric pressure‚ is a reaction mass that provides the thrust. All rockets have a reaction mass‚ which can vary from hot gasses that are expelled when a fuel is burnt (in the Space Shuttle’s SRB’s for example) to water in a water rocket. The

selected as input signals. A function of multi-sine with three different frequencies‚ 0.05Hz‚ 0.2Hz and 1Hz is used as the input signal. The equation is given and shows as below. Since impulse signals are hard to generate and might cause problem to the control plant‚ PRBS is introduced to mimic the behaviour of impulse signal. PRBS is also used in the experiment for system identification. PRBS is a binary sequence and considered to be similar to truly random sequence within a range of frequencies. A

shopaholism. Other words for this term include compulsive shopping or buying and shopping addiction. Most causes for compulsive shopping are psychological damages and should be treated immediately. Avoiding the issue can cause difficulties with finances and relationships. Shopping addicts sometimes have a hard time to stop spending. There are many penalties for compulsive buying‚ which usually continue long after a binge. Compusive buying can be devastating to relationships‚ marriages‚ jobs‚ family‚ and

Shoppers: According to Bonny Forrest a psychologist from San Diego‚CA‚ For Compulsive shoppers buying something creates a feeling related to the EUPHORIA that alcohol induces. Evidence: There was also a study done in 2006 at Stanford University that proved that about 6% of women and 5.5% of men are compulsive buyers. This mental disorder has not been studied extensively but it is thought to be an impulse control disorder. Evidence: April Lane Benson she is a New York psychologist and author of

Buying Motives Of Consumers There are different kinds of consumers. So‚ their wants and needs are also different. They buy goods or services to satisfy their needs. The causes and factors which stimulate consumer to buy certain goods or services is called buying motives. In fact‚ the motivating factor to direct consumer behavior is buying motives. Emotional Buying Motive Emotional buying motive depends on the emotion‚ feeling and attitude of the consumers. This type of motive is purely a psychological
