What is the bandwidth of the new satellite channels?
For the 256,000 bit per second discrete stereo channels, used for Standard Public Radio service, the RF bandwidth is 307.2 kHz, the audio bandwidth is 20 kHz. For the 128,000 bit per second mono channels, used for Standard Public Radio service, the RF bandwidth is 153.6 kHz, the audio bandwidth is 20 kHz. The demods also support data rates of 192 and 64 kbit/sec which won’t be part of Public Radio Standard Channel service. If an independent producer or distributor were to buy a channel of either of those sizes, and of the proper coding, the demod could receive them. The RF bandwidth for 64,000 bits per second is 76.8 kHz. The RF bandwidth for 192,000 bits per second is 230.4 kHz Of the four digital bandwidths listed above, only one of them (the 128 kbit mono channel) is equivalent to an analog channel in the old Public Radio Satellite System. This analog channel occupies 180 kHz of RF bandwidth and has an audio bandwidth of 15 kHz. So, the digital system is slightly more spectrum-effic
