$2.$ Given the following amplifier configurations $\backslash$& input signal $($Vin$)$

Sketch and label the input voltage $($Vin$)$ and output voltage $($Vo$)$ for each of the following configurations $-$ on the same waveform graph:

For each configurtaion: $(1)$ Specify type of amplifier and

$(2)$ determine the GAIN

a$.$ Configuration $($a$)$:

$"$S$1"$ set to $(1)$;

$"$ A $"$ is grounded;

Vin is connected to $"$C$"$

b$.$ Configuration $($b$)$: $"$S$1"$ set to $(2)$;

$"$ A $"$ is grounded;

Vin is connected to $"$C$"$

c$.$ Configuration $($c$)$: $"$S$1"$ set to $(1)$;

$"\backslash ($ C $\backslash )"$ is grounded; Vin is connected to $"\backslash ($ A $\backslash )"$
