Question

Write Arduino C code for AM transmitter and recievier using (1000KHz)AM frequency

Answer 1

Amplitude modulation transmitter

int Signal;
int A=2;
int t=0;
void setup(){
pinMode(4, OUTPUT);

}
void loop(){
analogWrite(4, AMSignal());
t++;
}

}

int AMSignal(){

int AM;

Signal=analogRead(5);

AM=(A+Signal)*cos(1000*t);
return AM;

}

reciever

int Signal;
int A=2; //Wert
int t=0;
int AM;

void setup(){

pinMode(4, INPUT);

}


void loop(){

while(1){
Signal=analogRead(5);

AM=(A+Signal)*cos(1000*t);
analogWrite(4, AMSignal());
t++;


}

}
