A PCM-TDM system multiplexes 32 voice band channels each with a bandwidth of 0-4kHz. Each sample is encoded with an 8-bit PCM code. UPNRZ encoding is used. What is the minimum sample rate, line speed (bits per sec), and min nyquist band width?
Given the vector field F(x,y,z) = 2zi + (x+y)j - yzk. S (oriented upward) is the part of the plane x + y + z = 1 above the triangular region with vertices (0,0,0), (1,0,0) and (0,1,0) and C is the boundary of S with positive (counterclockwise) o..
In a satellite radio system, 128 stations of stereo quality are to be packaged in one data stream. For each station, two(left and right) signals of bandwidth 15,000 hz are sampled, quantized, and binary coded into PCM signals.
How do you create a class in Java to enable its object to be persistent What are Java data streams and how are they used to facilitate storage and retrieval of persistent objects
An emitter follower, when driven from a 10 kohm source, was found to have an output resistance Rout of 200 ohm. The output resistance increased to 300 ohm when the source resistance was increased to 20 kohm.
