 +Frequency Modulation. The process of varying the carrier frequency with the modulation frequency thus enabling the signal to have a constant amplitude, mainly used at Very High Frequencies 90-110MHz broadcasts, this enables verygood noise control. More complex than AM as it requires a special demodulator to obtain the information.

 This a protection device to protect power supplies, cabling and devices from the effects of excessive current. Typically a short length of wire can carry the rated current indefinitely, but melts (blows) when the current exceeds the rating. A quick blow fuse will blow in a short time after the rating is exceeded and is used to protect sensitive components like semiconductors. A slow blow fuse can carry excess current for a considerable period (50% excess for half an hour is common) and is commonly used to protect cables- the fuse in a UK power plug is normally of this type. This a protection device to protect power supplies, cabling and devices from the effects of excessive current.
