Question:
(a) The conversion of a time varying analog audio signal into digital form is carried out using an electronic circuit known as a (signal) encoder. Draw a labeled block diagram of the encoder with a brief explanation of the components of the encoder.
(b) 5.1 tracks are used in Dolby's Surround Sound or for DVD movies in surround sound. What does the number "5.1"stand for?
(c) Define analytically the periodic function illustrated below in terms of F(t)
Hence, state the period and the amplitude at T=2ms.
(d) Most of the editing tools provide an assortment of effects that can help to improve sound quality or create unusual sound effects.
Describe the following sound effects: (i) Amplitude (ii) Balance (iii) Delay effects (iv) Reverb.
Determine self inductances of coils: The number of turns in two coupled coils A and B are 600 and 1700 respectively. While a current of 6 A flows in coil B, the total flux in
There is often a need to produce more than one voltage from a single supply using a voltage divider. For example, the memory components of many personal computers require voltages
Question: (a) A tube from one end of a differential pressure transducer is placed at the bottom of a cylindrical cup (D= 0.8m, H= 0.1m) to measure mass flow rate. The cup i
Q. Using the small-signal equivalent circuit of a BJT with gm = 0.03 S, β = 75, and VA = 65 V, a load resistor RL is connected from the collector to the emitter, as shown in Figure
Q. What do you mean by Nibble? The nibble is a collection of bits on a 4-bit boundary. It would not be a particularly interesting data structure except for two items BCD (binar
Question: (a) An FSK Scheme is used in a wireless transmission with the data bits 1011010. With the help of a labeled diagram, describe in detail the final output of the MSK
