QUESTION 8 What is the gain margin for G3(s)=100/(s(s+4)(s+8)) when connected with unity negative feedback and a controller gain of 0.29? Find the gain margin as the gain ratio, not dB. Give your answer to 2 d.p. Remember: GM=1/abs(G(jw_pc)) or GM (in dB)=-20log(abs(G(jw_pc)) where w_pc is the phase crossover frequency.

Assume we are writing a testbench for a sequential circuit that has three control inputs (cA, cB, cC) and a periodic clock (clk). If we define CLK_PERIOD as a localparameter with a value of 50 (nsec), write the testbench segment that would ensure all possible combinations of the control inputs were tested on a clock rising edge. This is can be done more elegantly if you define each time step in terms of the constant CLK_PERIOD. Your answer should include the statements that define clk, cA, cB, and cC over time. Hint: think of how you would show all combinations of three variables on a truth table and replicate that over time, where each combination is held over a timespan with a clock triggering edge.
Can I get assistance on how to plot this in matlab? Thank you.
5. Consider the following set of Boolean functions: W (p, q, r) = E(1,3, 5,7) X (p, q, r) = E(0,1,5,7) Y (p, q, r) = E(1,3,6) (a) Deduce the optimal ROM truth table for the above functions. (b) Draw the ROM logic diagram to implement the circuit.
2. Consider a unit-energy root-raised-cosine (RRC) pulse which spans over 8 symbol durations. We take 10 samples per symbol (sps) from this RRC pulse. Write an RRC filter function that employs pulse-shaping using the RRC pulse described above. (If there is a single symbol and s=[1 0], the energy of the corresponding length-81 samples vector should be equal to 1.) The parameters of the RRC pulse are roll-off factor, span, and samples per symbol. You should write your pulse-shaping function according to the prototype given below txFilt = myRRCFilter(s, rf, span, sps) where txFilt is the pulse-shaped signal (transmitted signal), s denotes the transmitted symbols, rf is the roll-off factor, span is the span of the filter, and sps is the samples per symbol.

Please written by computer source An LSTM with a single hidden layer has 2 neurons in all its gates. The forget gate weight matrix (Wf), the input gate weight matrix (Wi) and the output gate weight matrix (Wo) are all given. Wf=Wi=Wo=[[-0..8, 0, -0.3,-0.75, 0.26, 0.09];[0.05, -0.1, -0.9, 0, 0.85, 0.07]].Where the first two columns are the weights for the CEC memory (i.e Wfc/Wic/Woc) the following two columns are weights for hidden memory (i.e Wfh/Wih/Who) and the last two columns are weights for the input (i.e Wfx/Wix/Wox). The input pattern detection weights Wc are given by The input pattern detection weights Wc are given by Wc = [[0.8, 0.9, 0.3, 1];[0.3, 0.45, 0.7, 0.5]].
