What is Signal Delay?
Signal delay refers to the time taken for a signal to travel from the sender to the receiver. In the context of electronics and communication systems, reduced signal delay is crucial for faster data processing and transmission. This is especially important in applications like high-speed computing, telecommunications, and advanced biomedical devices.
How Does Nanotechnology Influence Signal Delay?
Nanotechnology plays a pivotal role in minimizing signal delay by leveraging materials and structures at the nanometer scale. The use of
nanomaterials, such as carbon nanotubes and graphene, offers superior electrical properties that significantly reduce resistive losses and improve signal propagation speed.
