Which binary signaling technique uses a scheme in which zero voltage represents a 0 bit and the voltage for a 1 bit does not dro

Answer:

In binary signaling, Non Return to Zero (NRZ) is the technique in which zero voltage is represented by 0 bit while high voltage is represented by 1 until the voltage level change from high to low.

Explanation:

There are different techniques to encode the signal for transmission between transmitter and receiver. These techniques includes return to zero, non return to zero. In return to zero technique, the if the voltage is high the signal will become 1 for half of the time period and then after half time period it return to 0.

In NRZ the signal is 0 if the voltage level is zero. In case of high voltage of the signal the binary bit remains 1 until the next zero voltage level arrive in the signal until the end of the time period of bit.

Write a program that simulates flipping a coin repeatedly and continues until three consecutive heads. are tossed. At that point
quester [9]

Answer and Explanation:

#include <iostream>

#include <string>

#include <time.h>

#include <vector>

using namespace std;

//Takes user info

//Toss coin(part 2)

bool coin_toss(double seed){

   double r;

   r = (double)seed/(double)RAND_MAX;

   //cout<<r;

   if (r<0.5) return true;

}

   char dummy = getchar();

 

   //part 2

   int num_toss;

   vector<char> toss_results;//store toss results

   bool result;//result of toss

   srand(time(0));

   while(true){
