Question

QUESTION 2 

You are asked to design an electronic circuit using operational amplifiers. There are two inputs to the circuit, \(V_{1}=0.1 \sin 100 t V\), and \(V_{2}=0.25 \cos 250 \pi t V\). The output of the circuit is required to be:

$$ V_{0}=-\sin 100 t+5 \cos 250 \pi t V $$

a. Draw diagram of the circuit you designed.

b. Calculate the values of the components.

QUESTION 3

 An inverting circuit is shown in the figure.

a. Derive an expression for \( v_{x} / v_{1}\)

b. Derive an expression for \(v_{o} / v_{x}\). 

C. Derive the expression for the voltage gain v_o/v₁
