A speed signal, band limited to 4 kHz and peak voltage varying between + 5 V and - 5 V, is sampled at the Nyquist rate. Each sample is quantised and represented by 8 bits.

Assuming the signal to be uniformly distributed between its peak to peak value, the signal to noise ratio at the quantiser output is

16 dB

32 dB

48 dB

4 dB

How are we getting the above values?I'm not very clear about the calculation of L . Shouldn't L also calculate to be 3?? Please clarify

A shaft of length 0.75 supported freely at the ends is carrying a body of mass 90 kg at 0.25m from one end. Assume E = 200 GN/m² and shaft diameter = 0.50 m. The static deflection at the wad point will be

0.1 × 10^-6 m

1.04 × 10^-4 m

1.02 × 10^-9m

1.25 × 10^-3m

Here in Question you mentioned shaft dia as 0.5 m and in solution you take as 0.05 m... how?

Which one of the following is correct about Tellegen's theorem?

It is concerned with type of elements.

It is only based on KCL.

It is only based on KVL.

It is based on both KCL & KVL.

Please type your answer before submitting.

The basic assumptions for Tellegen systems are the conservation of flow of extensive quantities (Kirchhoff's current law, KCL) and the uniqueness of the potentials at the network nodes (Kirchhoff's voltage law, KVL). So, I think option 4 is correct.
