Effect of Antenna Gain on Broadcasting Distance
Antenna gain is a measure of how much power is radiated in a particular direction by an antenna compared to a hypothetical isotropic radiator (an antenna that radiates equally in all directions). Antenna gain is usually expressed in decibels relative to an isotropic radiator (dBi) or a dipole radiator (dBd).
The difference between AM radio and FM radio
AM (Amplitude Modulation) and FM (Frequency Modulation) are two different methods of broadcasting radio signals, and they have several key differences
How to Compatible Analog and Digital Signals
What are analog signals and digital signals? Analog signals include: C-VIDEO multiplexing video signal, S-VIDEO separated video signal, YPRPB component video signal, security industry BNC interface, VGA interface, etc
How to distinguish digital signal from analog signal and conversion problem
There is a big difference between analog and digital signals. The analog signal uses a continuously changing value to represent the information to be explained;
Definition and difference of analog signal and digital signal
Do you know the difference between analog and digital signals? Before we know that, we must know what is an analog signal and what is a digital signal.
What does an analog signal mean?
It is mainly a continuous signal as opposed to a discrete digital signal. Analog signals are distributed in every corner of nature, such as daily temperature changes, while digital signals are artificially abstracted signals that are discontinuous in time.
