Question

3-10 A low-frequency sine wave voltage is the input to the following circuits. Sketch the anticipated output of each circuit.

Short answer

The anticipated output of the circuit is

Step-by-step solution

Part (a) . 

Write the expression for the input voltage.

$v_i=A\sin \left(\omega t\right)$ ...... (I)

Here, the input voltage is $v_i$, the amplitude of the wave is $A$, the angular frequency of the wave is $\omega$, and the time is $t$.

Write the expression for the output voltage of the circuit.

$v_0=-\frac{R_f}{R_i}{v}_i$ ...... (II)

Here, the output voltage is $v_0$, the input resistor is $R_i$, and the feedback resistor is $R_f$.

Substitute $A\sin \left(\omega t\right)$ for $v_i$in Equation (II).

$v_0=-\frac{R_f}{R_i}A\sin \left(\omega t\right)$

The below figure represents the anticipated output of the circuit.
