blocker Jamming to Signal Ratio Equation
The ratio of the desired signal power to the total power of interfering signals and noise, measured under specified conditions, at a specified point in the transmission channel. The signal is the signal jammer tool that carries the message, the carrier of the message. Broadly speaking, it includes optical signals, acoustic signals and electrical signals, etc.An unqualified transmitter will have a fairly wide spread of noise centered on the carrier, causing interference in the frequency band of a few megahertz.
Equations include deterministic signals and random signals. A signal is a tool for carrying messages and a carrier of messages. Broadly speaking, it includes optical signals, acoustic signals and electrical signals, etc. For example, the ancients used the billowing smoke produced by lighting the beacon tower to transmit the news of the enemy's invasion to the distant army, which belongs to the light signal; when we speak, the sound wave is transmitted to the ears of others, so that others understand our intention, which belongs to the sound Signals; various radio waves traveling in space, currents in the telephone network extending in all directions, etc., can be used to express various messages to the distance, which are electrical signals
