ABSTRACT
This chapter examines the alternatives to provide information that will help an engineer decide which is best for a particular situation. It shows that transmission of audio over an Internet Protocol network is subject to errors associated with jitter, packet loss, complete loss of connection, and sequence errors. The chapter focuses on the alignment of a new installation; a realignment is essentially the same after the point that a signal has been acquired. Frequency modulation (FM) techniques have been the mainstay in microwave studio-to-transmitter link (STL) communications for decades, but are clearly on the decline as the digital transition increases the complexity of STLs and transmitter-to-studio links. Microwave terminals are likely to be located at studios, earth stations, or TV transmitters, all of which are known, fixed sites. One of the major tasks required to engineer an STL system is the path analysis between the STL transmitter at the studio and the STL receiver location.
