As shown in the figure below, AC220V is stepped down to AC18V by T2, and then to DC25V after bridge rectification. DC25V is filtered by capacitors and inductors. In order to prevent the filter circuit
Help, the picture above is our current design, the LED light and the camera are attached to the PCB together, but the LED light-emitting surface is far away from the camera, and there will be dark ban
【Abstract】A multi-antenna orthogonal frequency division multiplexing (MIMO-OFDM) (terrestrial digital video broadcasting) system implementation scheme is proposed. By combining MIMO and OFDM technolog
