Webb20 maj 2024 · Propagation delays can refer to the time that is required for a signal to travel from its source to its destination. It can also refer to a logic gate delay, such as a “slow” NAND gate with lagging output state changes given the input state. This can cause problems in your design if the clock and the output pulses end up being out of sync. Webb22 apr. 2024 · Thus the RF wireless signals transmitted around or in the human body will suffer from body-shadowing effect, which will lead to significant signal attenuation [ 13, 14 ]. Moreover, the RF techniques radiate the signal via antenna, which is challenged for miniaturization. Another potential candidate is the inductive wireless coupling technique.
