Determine the output voltage for an op-amp comparator circuit with a non-inverting input reference voltage of + 2 VDC and an inverting input signal of - 1 VDC. The op amp reaches output saturation voltages of ±13 V at the limits.
Determine whether the system described by (1) y[n]=log(nx[n]), (2) y[n]=sqrt(n)*x[n+1], (3) y[n]=x[n-2]u[n], where a is an integer and |a|>1, is (i) memoryless; (ii) invertible; (iii) causal; (iv) stable; (v) time invariant; (vi) linear
Design a micro grid of PV rated at 100KW of power and at 230 V AC using a PV module with the following voltage and current characteristics. Determine the following: Number of modules in a string for each PV type Number of strings in an array for ea..
Describe the problem itself, the background of the problem,short literature review, the importance of solving that problem, etc.
(a) Determine the cone angle that will match the line to an infinite length biconical antenna. (b) For the cone angle of part (a), determine the two smallest cone lengths that will resonate the antenna.
After the breadboard has been completed, a cost analysis should be performed to determine the status of the design relative to the cost goals. Discuss the alternatives that can be considered if the breadboard design is already over the identified ..
