to clearly understand the signal, it is found that frequency content of the signal is well understood. For the analysis and processing of breathing sound which is recorded by the sensory audio reader (sensor), the Short Time Fourier Transform and wavelet transform is applied to it. And the programs were developed in MATLAB. Short time Fourier transform (STFT) is a Fourier related transform which is used to determine the sinusoidal frequency and phase content of the signal which changes over time.

I. INTRODUCTION (HEADING 1) Digital signals have transformed the world today, and in few areas is it as prevalent as it is in the music industry. Today’s analog-to-digital converters allow us to accurately store the physical, analog phenomena of sound as digital data, with high fidelity and perfect reproduction quality [1]. Digital audio storage is far more practical than analog audio storage for both the consumer and the professional alike. Digital audio is not vulnerable to noise, unlike analog
demonstrate the pulse code digitization and companding on a signal and to observe the effects of sampling depths and companding on the signal to noise ratio (SQR). INTRODUCTION PCM- In the pulse code modulation (PCM), the signal is a digitally represented analog signal in which the signal magnitude is sampled with uniform intervals. Each sample is quantized to the closest value of the digital signal. In the pulse code modulation, the signal is binary. The two possible states represented in PCM are
A filter is a lens accessory. You add it over your lens’ end. You would use one for many reasons. With a lens filter you could correct the colors in a photo, protect your lens, change the contrast, reduce glare, polarize, and much more, depending on the type of filter. There are also color, macro and UV filters. For example, if you are taking a black and white photograph you can add a red filter to increase the contrast. 1. What is a polarizing filter? What benefits does one have for photographs
Holt exponential smoothing modelling Simple exponential smoothing does not do well when there is a trend in the data, which is inconvenient. In such situations, several methods were devised under the name "double exponential smoothing" or "second-order exponential smoothing", which is the recursive application of an exponential filter twice, thus being termed "double exponential smoothing". This nomenclature is similar to quadruple exponential smoothing, which also references its recursion depth
they deal with the basics of electronics on which the whole field depends on. It was really challenging in the beginning to understand these basics. Once I got the hold of it, I enjoyed it and even the advanced subjects like image processing and digital signal processing were easy to me.

Components which relate time dependent parameters such as gain control or filters. Measurement results may suffer from degradation property and be inclined to be un reproducible To sufficiently track these difference modern digital receivers build estimates of the tone amplitudes and the steady value are completed at least 10 times a
Digital image processing is the exercise of computer algorithms to perform image processing on digital images, as a subcategory or field of digital signal processing. Digital image processing has various advantages over analog image processing. It permits a much spacious range of algorithms to be applied to the input data and can be avoid problems such as the build-up of noise and signal distortion during processing. Since images are defined over multi dimensions digital image processing may be modeled
fluoroscopy system is much more complex compare to common radiography system. The factors included are contrast, resolution, distortion and quantum mottle. Firstly, contrast of the image can be manipulated by adjusting the amplitude of the video signal. Amount of scatter radiation is the main factor to reduce the image intensified fluoroscopic contrast. Main causes of scatter radiation comes from scattered ionizing radiation, penumbral light scatter in the input and output screens and light scatter
The pathloss (LP) is the unwanted reduction in the signal strength during the propagation of the transmitted signal from the transmitter to the receiver. It relates the received signal power to the transmitted signal power. The maximum path loss is used to estimate the maximum cell range with a suitable propagation model, in GSM systems Hata Okumura propagation model is considered for calculating the maximum allowable pathloss whereas for CDMA, WCDMA and LTE networks COST 231 Hata model is considered
