MODULATION TECHNIQUES 1.4.1 FREQUENCY SHIFT KEYING (FSK) Frequency shift keying is a frequency modulation in which the digital information is transmitted by discrete changes in frequency of the carrier signal. This technology is used for the communication system such as caller ID and emergency broadcasts [19]. The binary FSK is the simplest FSK. BFSK uses a pair of discrete frequencies to transmit binary information. The 1 and 0 is mentioned as mark frequency and space frequency. The other forms

*Queen Kong: The poem presents the reader with a power shift from male to female but could also highlight that the story is not simply restricted to a male perspective. In this light‚ Duffy is‚ like in ‘Mrs Midas’‚ highlighting how certain members of society are exploited and how‚ despite popular belief‚ women often have control over men. This is reinforced when Queen Kong states how he is “my (her) little man”. This reveals her affection towards the man but also significantly displays his physical

term "red shift". When astronomers are explaining how far away a distant object is‚ they will usually say something like "The red shift of the galaxy (or other object) indicates that it is about 4 billion light years away". What does "red shift" mean‚ and how can it tell us how far away an object is? Since most of the things we look at in the sky are so far away‚ we cannot visit them and find out what they are made of‚ what temperature they are and so on. The way that scientists decide what a distant

and its impact on the subsequent evolution of the international political economy Following the Second World War‚ the Bretton Woods system was implemented as a means of monetary management among independent nation states. It was based on Keynesian economics and a shared belief in capitalism. Bretton Woods‚ BWS‚ was considered a necessary response to the anarchic protectionist and neomerchantilist policies favoured in the great depression of the 30s.
