Are you sure you should be begging for help on a midterm? Tests are supposed to indicate what YOU have learned, not what you have asked others to solve for you.

Of course, I can help you with that. It seems like you have a series of questions related to a midterm. From the format you've provided, it looks like you are working on some electrical circuit analysis or digital logic problems. Let's break down each question and explain how to arrive at the answer.

Q5.1: 1
It appears that this question asks for a straightforward answer of "1" without any context or further explanation. So, the answer would simply be 1.

Q5.2: Vil - Vol
For this question, it seems like you need to find the difference between two values, namely Vil and Vol. Vil refers to the input voltage at which the logic level is recognized as low, while Vol refers to the output voltage level when the logic output is low. To calculate the difference, subtract Vol from Vil: Vil - Vol.

Q5.3: Voh - Vih
In this case, you are asked to find the difference between Voh and Vih. Voh represents the output voltage level when the logic output is high, while Vih is the input voltage at which the logic level is recognized as high. To obtain the difference, subtract Vih from Voh: Voh - Vih.

Q5.4: Vih - Vil
To determine the answer to this question, subtract Vil from Vih. As mentioned earlier, Vih denotes the input voltage level required for the logic level to be recognized as high, while Vil represents the input voltage at which the logic level is recognized as low.

Q5.5: [(Vs * 2 * Ron) / VoL] - (2 * Ron)
For this question, you need to calculate a numerical value using the following formula:
[(Vs * 2 * Ron) / VoL] - (2 * Ron)
Here, Vs is a variable representing a voltage source, Ron is a variable corresponding to the resistance value, and VoL denotes the output voltage level when the logic level is low. To find the answer, substitute the given values for Vs, Ron, and VoL into the equation, and then perform the necessary arithmetic calculations, following the order of operations (parentheses first, then multiplication and division).

Q5.6: [VS^2 / (RON + RPULLUP)]
Similar to the previous question, this problem requires you to calculate a result using the given formula:
[VS^2 / (RON + RPULLUP)]
In this equation, VS represents the voltage source, RON denotes the resistance value, and RPULLUP is the resistance value of a pull-up resistor. To solve this question, substitute the given values for VS, RON, and RPULLUP into the equation, and then calculate the result by following the order of operations.

Remember, it's essential to carefully read and understand each question and any given context or variables. Once you have a solid understanding of the problem, plug in the values and follow the calculations step by step to obtain the final answer.
