Look at the controls on your toaster and describe what each does.

Consider how these might be replaced with an LCD screen. What would be gained and lost from changing the interface in this way?

If a car agency sells 50% of its inventory of a certain foreign equipped cars with air bags. Find out Probability mass function (P.M.F) & cumulative distribution function (C.D.F) of the next 4 cars to be sold

How can we calculate the internal resistance of a wheatstone brigde given that Resistance 1=Resistance 2=Resistance 3=Resistance 4=1000 ohms and a galvanometer can detect as low as 0.1 milliamperes?

 A 220V, 50 Hz, 6 pole, Y connected alternator with resistance 0.06 Ω per phase gave

the following data for open circuit and Short circuit characteristics.

An educational institution wish to maintain a database of its students, the database is divided into a members of classes whose multiple relationships are shown in fig.1,find:

a-Initialize the five data members by using constructor? b-Calculate average of two marks (using friend function)? c-Display all database information where the student is successful?

Consider the LTI system

𝑦 𝑛 = 𝑥 𝑛 + 1 + 2𝑥 𝑛 + 𝑥 𝑛 − 1 − 𝑥 𝑛 − 2

What would be the response for the input as shown in figure

A Zener diode regulator circuit

must

provide a constant voltage of 12V, across

a 250Ω load resistor. The circuit uses a 24V input DC source, a 12V Zener

diode and a 50Ω series resistance. Calculate the minimum acceptable power

rating of the Zener diode.
