Signal blocker Jamming Explained
Signal interference is a physical quantity that represents messages in current communications. For example, electrical signals can represent different messages through changes in amplitude, frequency, and phase. Regardless of factors such as attenuation, delay, and noise, the signal through this channel will be undistorted. However, if a square wave with a fundamental frequency of 1kHz, the signal jammer will definitely be distorted through the channel; if the square wave signal has a fundamental frequency of 2kHz, but the highest harmonic frequency is 18kHz, the bandwidth exceeds the channel bandwidth, and its higher harmonics will be filtered out by the channel.
The bandwidth only needs 5kHz, which is much smaller than the channel bandwidth. Can it pass the channel well? In fact, when the signal is transmitted on the channel, the fundamental frequency is filtered out, and only the harmonics can pass through, and the signal waveform must be Unattractive.
