Since the UWB (Ultra Wide Band) system uses a broadband of more than 500MHz to transmit data at high speed, the UWB antenna must have good frequency characteristics. In recent years, OFDM (Orthogonal
Recently, news about nuclear radiation in Fukushima, Japan has been all over my friend circle. It is said that the highest radiation can kill people in tens of seconds. Here is a short video to share
Question 1: I use the STM32F103 series microcontroller to output 3 50% duty cycle PWM waves, but the transmission distance is about 80cm, and ordinary wires are used. So after adding a NAND gate to th
[table=98%] [tr][td]As the title says, does this require the use of a certain register bit, to read it before transmitting, and then decide according to the situation? Please help! ! ! ! [/td][/tr] [/
[b]0 Introduction[/b] In recent years, the huge demand for frequency sources in the communication industry and the widespread application of frequency sources in the military industry, coupled with th
Using MLC flash chips can reduce the cost of SSDs and increase their speed, but it also sacrifices relative stability and lifespan. However, it is still highly recommended for use in situations where
