Q. What are the different types of distributing frames used in exchanges?
Ans:
Different distribution frames used in exchange are displayed in figure. Each subscriber in a telephone network is connected generally to the nearest switching office by a dedicated pair of wires. Subscriber loop denotes to this pair of wires. It would be unwisely to run physically independent pairs from each subscriber premises to exchange. It is far easier to lay cables comprising a number of pairs of wires for different geographical locations and run individual pairs as needed by subscriber premises.
Q. The magnitude spectrum of a continuous image is as given below. a) Sketch the frequency response of the sampled spectrum if ωs =1.5 ωm along x and 3ωm along y directions
Q. Determine L and C of the band pass filter circuit of Figure to have a center frequency of 1 MHz and a bandwidth of 10 kHz. Also find the Q of the filter.
Plug and Socket Condition : In the same way that your knowledge of flexes and fuses is wasted if you don't care to ensure that flexes and cables are routed safely and sensibly, so
Q. Explain working of Shaded-pole motors? Shaded-pole motors: The least expensive of the fractional-horsepower motors, generally rated up to 1 / 20 hp, they have salient stator
Design a low noise amplifier using an Infineon RF transistor BFP640. The amplifier is to be used to amplify the L2 GPS signal and so the centre frequency is 1227MHz and bandwidth 4
