System level control design philosophy is presented for multichannel and two-way transmission systems. Techniques for channel selection are introduced. Appendix II end III covers these techniques. These techniques are used to reduce the effects of second-order and third order distortion products. Reasons for not standardizing pilots are clarified in conjunction with multichannel requirements and pilot placement.
Amplifier design approaches follow to fulfill system requirements. A novel automatic gain control (age) amplifier design incorporated at Anaconda Electronics Company is discussed. Design techniques are used which provide level stability and desirable transient response.
New amplifier design approaches are presented. These are termed reverse gain control amplifier and weighted age amplifier.
