Basic Model of One Clock

The basic implementation of the ETSI model shown in figure 7.1 in SPW is shown in figure 7.2

By comparing figures 7.1 and 7.2 the basic correspondence is evident. In actual fact, an extra $\sqrt{f_0}$ gain block was subsequently added to the top branch due to the initial results obtained and the subsequent examination of the behaviour of filter A. Noise generator blocks were also eventually used to generate the white gaussian noise of the fly rather than from file to preserve file space. Thus the basic model was actually as shown in figure 7.3
