A) when u modulate some thing you vary it
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.
Merging files involves combining two or more files while maintaining the sequential order of the records.
<h3>What is
Merging files?</h3>
Merging is known to be the act of of taking two or a lot of groups of data in the method of a file or folder, and adding them together into a single file or folder,
There are different kinds of files that exists. A computer file is one that comes in different format and sizes as well as its function. To merge connote to put two or more things together.
Note that, Merging files involves combining two or more files while maintaining the sequential order of the records.
