PCM CODING/COMPANDING Q1. a)i) The process of quantisation introduces an error or noise component into the quantised signal. Derive an equation for the mean-squared quantisation error in terms of the quantization interval ‘a’. ii) Hence show that the peak signal-to-quantisation noise ratio (SQNR) is SQNR = ( 6n + 4.8 ) dB Where 2 n is the number of quantisation levels. b)i) Linear quantisation is used prior to binary PCM encoding of an analogue baseband signal which has

London murders: a predictable pattern? Four stabbings to death in a single day. Ninety murders in 7 months. Shocking figures—or are they? Knife crime makes the headlines almost daily but are Londoners really at increased risk of being murdered? David Spiegelhalter and Arthur Barnett investigate— and find a predictable pattern of murder. Violence in London attracts headlines. After four people were murdered in separate incidents in London on July 10th‚ 2008‚ BBC correspondent Andy Tighe said “To

The objectives of this report are to diagnose their current inventory control strategy on DC‚ facility and site‚ analyze their improved new policy and propose a better strategy to inventory management and allocation. Poisson distribution is implemented to describe the demand assumption. The three main indexes we use to evaluate a strategy are fill rate‚ total inventory cost and expected downtime. Based on our analysis‚ the current old policy maintains the fill rate
