Texas has a wide inhabitants who has lived on each side of the border and created a folkloric combine that makes Texas distinct. either side of the Border will get its identify from its emphasis on lately researched Tex-Mex folklore. yet we realize that Texas has different borders in addition to the Rio Grande. We use that identify with the folklorist's wisdom that each one of this state's songs, stories, and traditions have lived and prospered at the different aspects of Texas borders at one time or one other sooner than they crossed the rivers and grew to become "ours.

This is the famous Nyquist theorem on sampling (also called the Shannon theorem). 2). 2, 2b). 2, 3b) can be seen to contain the same spectrum as the analog signal, together with repetitions of the spectrum modulated around multiples of the sampling frequency. As a consequence, low-pass ﬁltering can completely isolate and thus completely recover the analog signal. 3 show two sine waves (bottom traces) and their sampled equivalents (top traces). 3a, in both cases restitution of the original signal is perfectly possible.
2 Quantization stage characteristics. however, such overﬂows or underﬂows are avoided by careful scaling of the input signal. So, in the general case, we can say that: –Q/2 < e(n) < Q/2 where e(n) is the quantization error for a given sample n. 3). 3 Probability density function of quantization error. 4). In this manner, the quantization error is often called quantization noise, and a ‘signal-to-quantization noise’ ratio can be calculated. 4 Analogy between quantization error and noise. 76 A 16-bit system, therefore, gives a theoretical signal-to-noise ratio of 98 dB; a 14-bit system gives 86 dB.
Editing of the recording is performed on a digital audio editor by means of digital audio processors and VTRs. The ﬁnal result is stored on a VTR tape or cassette. The cutting machine used is a digital version. 17 A short history of audio technology Figure XIV Digital audio editing and record production. When the mixer is replaced by a digital version and – in the distant future – a digital microphone is used, the whole production system will be digitized. Digital audio broadcasting Since 1978, FM broadcasting stations have expressed a great deal of interest in digital tape recorders, realizing the beneﬁts they could bring almost as soon as they had been developed.
