Mutual inductance coupled phase frequency discriminator circuit
Mutual inductance coupling phase frequency discriminator Mutual inductance coupling phase frequency discriminator is also called Foster-Seeley frequency discriminator. Figure 7-41 is its typical circuit. The phase shift network is a coupling loop.
Auto spare lamp kits are extra lamp pieces that can be used to replace a piece that broken. There are many different bulbs and fuses in one spare lamp kits. For example, there are one H4 for headlight, one S25 singe filament for signal light, one dual filament S25 for stop light, one G18.5 for truck light or license plate light, one T10 for interior light or side indicators light and two different types of fuses that can replace the burned fuse. The customers will review what specs their own vehicle have and choose which to buy. Having a spare lamp in the car is like buy a insurance, because every light on the car has its specific purpose, which means any broken bulb might put the driver and others in a very dangerous situation. Highly recommend have one kits in the car.
