Sender and receiver are able to communicate with each other. Both of them are in ____________
Interference range
Detection range
Transmission range
The received power of the signal is high such that it can be detected but communication is not possible due to high error rate. The signal is in ____________
Interference range
Transmission range
Detection range
Find the correct relationship:
Et – Error rate in transmission range
Ed – Error rate in detection range
Ei – Error rate in interference range
