How to distinguish between analog and coaxial

There are obvious differences between simulated and network. Hangzhou right angle Cable Technology Co., Ltd. has sorted out the following information, hoping to help you. There is a difference between coaxial and analog in the recorded coding. The analog can't go to D1, and the coaxial can go to more than 720p lines. The network interface is network switch RJ45, and analog and coaxial are BNC heads. The analog host can only use the analog head, and the coaxial host can use the coaxial head or the analog head.

The coaxial line is a shielded and non dispersive structure, and the main mode of the guided wave in the coaxial line is TEM wave, but it can also transmit TE mode and TM mode. Its cut-off frequency is zero, and the corresponding cut-off wavelength tends to infinity. It is a double conductor transmission line composed of two coaxial inner and outer conductors and dielectric in the middle. Generally, the outer conductor of the coaxial line is grounded, and the electromagnetic field is limited between the inner and outer conductors, so the coaxial line basically has no radiation loss and is almost free from external signal interference. Its working band is wider than that of two-wire transmission, and can be used in bands larger than centimeter wave. Coaxial lines are widely used in the design of broadband feeders and components mainly in the form of TEM mode. When the wave length of the transmission signal is greater than the length of the transmission line, the magnitude and phase of the current (or voltage) at each point on the transmission line can be approximately the same. At this time, the effect of distribution parameters does not need to be considered. However, when the wavelength of the transmission signal and the length of the transmission line can be compared with each other, the size and phase of the current (or voltage) at each point on the transmission line are different, showing the distributed parameter effect. At this time, the transmission line must be treated as a distributed parameter circuit, which means that TE and TM modes will appear in the coaxial line, that is, the high-order modes of the coaxial line.
