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 is y(t)

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

The casual‚ self-venting‚ adolescent depiction of an absurd event that unfolded in a small town grocery store is a peculiar and yet entertaining read for all audiences. The theme of this story has to do with adolescent stressors‚ choices and consequences‚ and standing up for what one

C H A P T E R Finite-State Machines and Pushdown Automata The finite-state machine (FSM) and the pushdown automaton (PDA) enjoy a special place in computer science. The FSM has proven to be a very useful model for many practical tasks and deserves to be among the tools of every practicing computer scientist. Many simple tasks‚ such as interpreting the commands typed into a keyboard or running a calculator‚ can be modeled by finite-state machines. The PDA is a model to which one appeals when
