Q. Explain about Hybrid network?
Hybrid network (sometimes known as a hybrid coilor duplex coil) in a telephone set is a special balanced transformer used to convert a two-wire circuit(the local loop) in to a four wire circuit(the telephone set) and vice-versa, hence enabling full duplex operation over a two wirecircuit. Essentially, hybrid network separates transmitted signals from received signals. Outgoing voice signals are typically in 1-V to 2-V range, whereas incoming voice signals are typically half that value. Another function of hybrid network is to allow a small portion of transmit signal to be returned to the receiver in the form of a sidetone. In sufficient sidetone causes speaker to raise his voice, making telephone conversation seem unnatural. Too much side tone causes speaker to talk too softly, thus reducing the volume that listener receives.
#quesFind a minimum two level, multiple-output AND-OR gate circuit to realize these functions (eight gates minimum). F1(a,b,c,d) =Sm(10,11,12,15) +D (4,8,14) F2(a,b,c,d) =Sm(4,11
In this case, the armature is connected in series with the field coils. Thus I a = I f = I NB. At starting, the back emf is zero (because the m
