Abstract
Many shortcomings in the received audio, video, and/or data stream of a transmission resulting from noise, reflections, and terrain limitations cannot be controlled by the equipment design engineer or the operating maintenance engineer. However, other problems can be prevented through proper application of vacuum tube devices and proper equipment adjustment. The critical performance parameters for a transmission system include:
-
Output power
-
Transmission line/antenna VSWR
-
Frequency stability/accuracy
-
Occupied bandwidth
-
Distortion mechanisms, including total harmonic distortion (THD), intercarrier phase distortion (ICPM), and quadrature distortion
-
Differential phase and gain
-
Frequency response errors
-
Envelope delay
