Q. Explain the basic architecture of digital switching systems. Explain in detail companding.
Ans:
A simple N X N time division space switch is displayed in Figure. Switch can be represented in an equivalence form as a two-stage network with N X 1 and 1 X N switching matrices for first and second stages corresponding as displayed in Figure. Network has one link interconnecting the two stages. Every inlet/outlet is a single speech circuit corresponding to a subscriber line. Speech is carried as PAManalogue samples or PCM digital samples, occurring at 125-µs intervals. When PAM samples are switched in a time division manner, switching is called analogue time division switching. If PCM binary samples switched, then switching is termed as digital time division switching. In Figure, the interconnected by a suitable control mechanism and speech sample transferred from the inlet to the outlet.
why we plot graph to find bandwidth is drawn b/w av/avmax v/s frequency not av v/s frequency?
Q. Explain the action of a pn-junction with bias. Consider both the forward bias and the reverse bias, and use sketches wherever possible.
NPN BJT with forward-biased: An NPN transistor can be referred as two diodes along with a shared anode. In common operation, the base-emitter junction is forward biased and th
Determine the node voltage: Determine the node voltage V and then current flowing through each element by using KCL. Solution Apply KCL at the node whose voltage is V.
