A nice question. Well, we can reduce the noise or we can increase the signal. We assume you are using components that are inherently low noise in themselves. Consider a passive antenna. A simple...
A receiver receives a desired signal always in the presence of electronic noise, which is everpresent. If the signal becomes too weak relative to the noise, or other noise-like signals in the receive...
Noise signal is any signal which interferes with the main signal and does not give any important information.Signal should always be twice to that of noise.
