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.
