Nyquist and Shannon Capacity: Transcript


1 A very important consideration in data communications is how fast we can send data in bits per second over a channel Data rate depends on three factors 1 The bandwidth available 2. Mapping If we take a complex number on the splane and substitute into a function an other complex number results eg substitut ing 4 3 into 2 1 yields 16 30 Contour Consider a collection of points called a contour A Contour A can be mapped Nyquist olar plots olar plot of the frequency resp onse pro duces curv with frequency as parameter relating the oin ts on the olar plot to the appropriate oin ts on the Bo de plots see Fig 1 The Nyquist plot con tains the same information as the Bo DIGITAL COMMUNICATION.
