1. 1. Approach for frequency response-calibration for microphone arrays

   University essay from KTH/Hälsoinformatik och logistik

   Author : Jacob Drotz; [2023]
   Keywords : microphone array; frequency response; calibration; sine sweep; inverse filter; digital signal processing DSP ; convolution; Fast Fourier Transform FFT ; Discrete Fourier Transform DFT ; acoustic measurements; audio engineering; mikrofonarray; frekvenssvar; kalibrering; sinussvep; inverterat filter; digital signalbehandling; faltning; Fast Fourier Transform FFT ; Discrete Fourier Transform DFT ; akustiska mätningar; ljudteknik;

   Abstract : Matched frequency responses are a fundamental starting point for a variety ofimplementations for microphone arrays. In this report, two methods for frequencyresponse-calibration of a pre-assembled microphone array are presented andevaluated. READ MORE

3. 2. Assessment and evaluation of heterogeneity in data from immune infiltration spatial niches in lung cancer

   University essay from Lunds universitet/Matematisk statistik

   Author : Mahta Keivani Najafabadi; [2023]
   Keywords : Mathematics and Statistics;

   Abstract : The protein biomarker expressions in three types of sampled immune INFILTration spatial niches in lung cancer tissue were measured using the new technology Digital Spatial Profiler (DSP). The three types of immune INFILTration that were observed in lung tumors were STROMA identified as immune cells separate from tumor cells, Tertiary lymphoid structures (TLS) identified as dense structures of organized immune cells and finally Infiltraterate where immune cells dispersed among and in direct contact with tumor cells (INFILT).

4. 3. Development of an embedded system platform for signal analysis and processing

   University essay from Uppsala universitet/Signaler och system

   Author : Philip Lind; [2023]
   Keywords : Digital signal processing; DSP; digital filter; FIR; IIR; Butterworth; Chebychev; windowed sinc; Digital signalbehandling; DSP; digitalt filter; FIR; IIR; Butterworth; Chebychev; sinc; fönstermetoder;

   Abstract : Information is often stored and transmitted through electrical signals. This information may need refinement, which may be done by processing and altering the electrical signals, in which it is transmitted. When refining a signal, a frequency selective filter is often used. It can be implemented through digital signal processing (DSP). READ MORE

5. 4. Design of auxiliary communication for audio between computers and DSPs : Programming and optimization of computational resources

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Eriksson Janze Oscar; [2023]
   Keywords : DSP; Audio-communication; Auxiliary; AUX; phone connector; USB-audio; STM32; ADC; AD-converter; filterbank; hearing aid; signalprocessor; ljudkommunikation; ljudkabel; AUX; USB-ljud; STM32; hjälpmedel; ADC; analog-till-digital-omvandlare;

   Abstract : This thesis report is about designing a prototype and establishing audio communication between a computer and Digital Signal Processor (DSP) using two preamp circuits using both auxiliary and USB connection. The paper gives the reader an overview on how audio is transmitted from a computer, through the system and to the desired output. READ MORE

6. 5. Introducing Machine Learning in a Vectorized Digital Signal Processor

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Linnéa Ridderström; [2023]
   Keywords : Digital Signal Processor DSP ; Application-Specific Integrated Circuit ASIC ; Machine Learning; Deep Learning; Convolutional Neural Network CNN ; Very Long Instruction Word VLIM ; Single Instruction Multiple Data SIMD ; Digital Signalprocessor DSP ; Applikation-Specifik Integrerad Krets ASIC ; Maskininlärning; Djupinlärning; Konvolutionella Neurala Nätverk CNN ; Very Long Instruction Word VLIW ; Single Instruction Multiple Data SIMD ;

   Abstract : Machine learning is rapidly being integrated into all areas of society, however, that puts a lot of pressure on resource costraint hardware such as embedded systems. The company Ericsson is gradually integrating machine learning based on neural networks, so-called deep learning, into their radio products. READ MORE
