It is a misconception, to think that the bandwidth of an analog channel is higher than a digital one. It is actually reversed, where the /effective/ bandwidth of a digital channel is higher than an equivalent analog channel. The number of bits required goes to the root of Shannon's information theory. We see how effective it is in our daily life everywhere and it is better than analog. Telephony has been digitalized completely today. Television has transitioned from analog to digital, freeing more than 50% of the bandwidth, while increasing the number of channels. Radio will follow (currently running parallel). -- Greetings Bertho (disclaimers are disclaimed) ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
