Distinguish between open-loop and closed-loop systems

The simplified SOP form of the Boolean Expression (A+B+T(A+B+C).(A+B+T) is : (A+B.C)

Program a circuit where a yellow LED light will turn on when a button is pressed 4 times and remain on for 4 seconds. Then, a red light will flash at 2 Hz for 8 seconds.

Here MATLAB code for the following.   Write a program to calculate convolution of 2 signals in the time-domain.（Note: using own code, not internal function, is required）.

Apply DeMorgan's theorems to each expression: a. AB (C+D b. AB (CD + EF) c. (A + B + C + D) + ABCD

Please answer the below images with a detailed solution and a full explanation. Answer the question like you are answering an engineer's question. For the coding questions, please use both Java and C++.

A circuit is constructed with four resistors, one inductor, one battery and a switch as shown. The values for the resistors are: R1 = R2 = 72 Q, R3 = 61 Q and R4 = 99 Q. The inductance is L = %3D V L 549 mH and the battery voltage is V = 24 V. R3 1) The switch has been open for a long time when at time t = 0, the switch is closed. What is l1(0), the magnitude of the current through the resistor R1 just after the switch is closed? A Submit 2) What is 1(o0), the magnitude of the current that flows through the resistor R1 a very long time after the switch has been closed? A Submit 3) What is VL(0), the magnitude of the voltage across the inductor just after the switch is closed? V Submit 4) What is IL(0), the magnitude of the current through the inductor after the switch has been closed for a very long time? A Submit 5) What is I2(0), the magnitude of the current through the resistor R2 just after the switch is closed? A Submit
