Digital modulation and dynamic range
|
Measurement dynamic range is one of the essential performance parameters of a receiver or spectrum analyzer. Most published material, however, has addressed dynamic range in terms of sinusoidal signals rather than digitally modulated signals. While optimum dynamic range can be achieved by reducing noise at the narrowest measurement bandwidth, this does not work for digital modulation where signals behave as noise and the signal-to-noise ratio (SNR) is independent of the measurement bandwidth....
