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.
total = 0
for x in range(20, 91, 10):
total += x
print(total)
I hope this helps!

Answer: Please see below as the answer is self-explanatory
Explanation:
In a telephone system, we call signaling to all signals that are originated within a telephony circuit, that are not part of the conversation between the calling parties.
We include in this broad category, the signal generated by the calling party when he picks up the phone, the call tone sent to him by the switch (or the busy tone if the call can't be established due to blocking), the digits that identify the called party, the ringing signal that informs the called party that someone is trying to reach him for a call, among others like are defined in the SS7 or the different 2G/3G/4G Cellular standards.
The importance of the signalling is pretty obvious; without these signals, it will be virtually impossible to set up a connection between the two parties.
