Q. Explain about Virtual Circuit Switching?
Virtual Circuit Switching
- All packets belong to a message (or) session is preserved.
- Single route is selected between source/destination.
- All packets obtain that route to reach destination.
- It requires a call setup to establish a virtual circuit. (Either permanent or switched type)
- Uses virtual circuit identifier for routing.
Error detection and correction The digital traffic stream of second generation systems also lends itself to the use of error detection and correction methods. The result can be
Consider a signal x(t) = 10 cos(2πfct + 4 cos 2πfmt). Assume frequency modulation. The message frequency fm = 2:3 kHz. Calculate the modulation index and find the bandwidth when
