“…Ogungbenro et al [16] explained some of the advantages of using emulators on digital techniques, namely the original appearance, nuances and behavior of digital objects are maintained, the initial capital on emulator production is greater but other expenditures will be more efficient, reducing laboratory usage time, many emulators have been developed well and licensed, emulators can be used on variety of device systems, the physical needs of emulators can be reduced so that they can reduce costs and practice time, most emulators have large data memory and can provide many simulated electronic components.…”
