RISC architecture
RISC stands for reduced instruction set computer. It is a type of microprocessor architecture which utilizes a small, highly optimized instructions set rather than a more specialized set of instructions normally found in other types of architecture. Hence
Advantages, disadvantages and applications of FHSS
Advantages: There are some advantages of frequency hopping spread spectrum (FHSS) which are given below, It can be programmed to avoid some portions of spectrum . FHSS needs shorter time for acquisition. Very large bandwidth. Disadvantages: There
Difference between slow frequency hopping and fast frequency hopping
Following are the difference between slow frequency hopping and fast frequency hopping. Slow frequency hopping Fast frequency hopping In slow frequency hopping, multiple symbols are transmitted in one frequency hop. In fast frequency hopping, multiple hops are
