Consider your ID $=$ AB$-$CDEFG$-$H$.$ Choose the appropriate digits when solving the problems.

$1.$ Problem $1$:

An audio transmitter is provided to send the voices of a user over a long distance. The voice signal $[$peak value $=$

$($EFG $+100)$ mV$]$ is added to a dc voltage having value of $[$H$+5]$ V mixed with line voltage $(220$ V rms$)$ before

transmission. This mixed signal after deducing the dc value will work as the $($intermediate$)$ output of the transmitter.

The mixed signal with restored dc value will be found at the end of the receiver.

$($a$)$ Find the circuits necessary in both transmitter and receiver sides.

$($b$)$ Compute the circuit diagrams of part $($a$)$ sketching different signals, components and analyzing the process of

the deduction of signals at transmitter and restoring of the signals at receiver side of the systems with different

practical diodes $[$Si$,$ Ge$,$ GaAs$].$ I need a solution based on clipper clamper circuits.
