Please draw the graphs so I can understand the shape! Figure $4$ is included in the pictures. Thanks in advance!

For the full$-$wave bridge rectifier circuit illustrated in Figure $4$ assume that there is

a $0\mathrm{.}7$ V drop across the diodes when they are forward biased.

a$.$v$\_($S$)$ is a $1$ kHz sinusoid with an amplitude of $2\mathrm{.}5$ V and R$=10$k$\backslash$Omega $,$

sketch the input v$\_($S$)$ and the output v$\_($O$)$ on a single graph, labeling important

points on the time and voltage axes for a couple of cycles of the sinusoid$.$

b$.$Longrightarrow sketch the input v$\_($S$)$ and the output v$\_($O$)$ on a single graph, labeling important

points on the time and voltage axes for a couple of cycles of the sinusoid$.$

c$.$Longrightarrow Describe the similarities and differences between the two cases.
