…………………… is used to describe the light gathering or light collecting ability of an optical fiber.

In VHDL all the statements written inside a process statement are …….

In what order the elements of a pushdown stack are accessed ?

……………. is defined as the time delay that a signal component of frequency undergoes as it passes from the input to output of the system.

A PN junction in series with a 100 ohm resistor is forward biased so that a current of 100 mA flows. If voltage across the combination is instantaneously reversed to 10 V at time t = 0, the reverse current that flows through the junction at t = 0 is approximately given by :

For a 3 μm – diameter optical fiber with core and cladding indexes of refraction of 1.545 and 1.510, respectively. The cut off wavelength is :

As compared to a full wave rectifier using 2 diodes, the four diode bridge rectifier has the dominant advantage of :

Four voice signals, each limited to 4 kHz and sampled at Nyquist rate, are converted into binary PCM signal using 256 quantisation levels. The bit transmission rate for the time division multiplexing signal will be :

The process of imitating one system with another so that the imitating systems accepts the same date, executes same programs and achieves same results as the imitated system is known as :

The Thevenin and Norton circuits are :
