Ferrites for Entertainment Applications-Radio and TV

Summary

We have outlined some of the ferrites used for entertainment applications. We have confined these primarily to radio and television applications. Video cassette recorders (VCR’s) which may be related to TV uses will be covered in the chapter on magnetic recording which is closer to the function of the ferrite. Some of the applications (such as IF transformers) in the present chapter are really related to the low-level uses described in Chapter 10. Still others such as TV flyback transformers are also related to the high power applications discussed in the next chapter. However, for the sake of keeping materials related to their functions in the devices, we have decided to both of these topics in the present chapter. The power magnetics discussed in the next chapter may be common to many of the other applications since they supply the power needed to drive them. It is also the area which is very timely now as the change from linear to switching power supplies accelerates.
