Assignment-2 1. Obtain the direct form-I, direct form-II, cascade and parallel form realizations of the LTI system governed by the equation $ y(n)=\frac{13}{12} y(n-1)-\frac{9}{24} y(n-2)-\frac{1}{24} y(n-3)+x(n)+4 x(n-1)+3 x(n-2) $. 2. Realize the given system in cascade and parallel forms \[ H(z)=\frac{1+(1 / 3) z^{-1}}{\left[1-(1 / 2) z^{-1}+(1 / 3) z^{-2}\right]\left[1-(1 / 3) z^{-1}+(1 / 2) z^{-2}\right]} \] 3. Obtain the direct form-l, direct form-II, cascade and parallel form realizations for the following system. \[ y(n)=0.75 y(n-1)-0.125 y(n-2)+6 x(n)+7 x(n-1)+x(n-2) \] 4. Draw the direct form and linear phase Realization of FIR filter having the following impulse response \[ h(n)=\delta(n)-\frac{1}{4} \delta(n-1)+\frac{1}{2} \delta(n-2)+\frac{1}{2} \delta(n-3)-\frac{1}{4} \delta(n-4)+\delta(n-5) \] 5.

Suppose we wanted to test the hypothesis that a control group of cancer patients (Group 1) would report higher mean pain ratings than an experimental group receiving special massage treatments (Group 2). Using the following information, compute a t statistic for independent groups: Group 1: Mean = 76.5 Standard deviation = 13.1 N =20 Group 2: Mean = 72.1 Standard deviation = 14.7

TCLR (Q)=300+\frac{(Q^2+1)(Q+2)}{Q^2} a. What is the long run average cost, average variable cost and marginal cost? b. Suppose that there are only two inputs, capital and labor, and that in the TCLR function given above, the price of capital is 100 and the price of labor is 10. Now suppose that the price of capital drops to 50 and the price of labor drops to 5. Either give the new ACLR, VCLR, and MCLR or argue why it is impossible to determine. c. Suppose instead that the price of capital drops to 50 while the price of labor goes up to 20. Either give the new ACLR, VCLR, and MCLR or argue why it is impossible to determine.
