    Blood cell monitoring based on FPGA, implemented using VHDL
    (Journal of Research in Engineering and Applied Sciences, 2017-10) Khan, Zarrarahmed; Pathan, Siraj; Pathan, Riyaz; Ali, Zeeshan; Khadase, Rahul; Alvi, Rizwan
    This paper showcases a system in the medical field which will assuage the limitations in today's blood cell monitoring since everything will be done digitally. Our work is a combination of image processing and its implementation in hardware. This system will not only store the information of patients' blood components, but it will also indicate the deficiencies using an Alert signal. Area wise storage of patients' information will help in Area Wise Analysis of data. This blood cell monitoring system is designed on Xilinx ISE 14.6 using VHDL and implemented on Spartan 3A based FPGA (Field Programmable Gate Array). In medical camps it is very difficult to test blood samples of thousands of people with pharmaceutical techniques and at that time this Blood Cell monitoring system will give proper ease to test blood samples as it will require few microscopic pics only and image processing will be done at ultra-high speed since we are using the FPGA. FPGA will itself process images, store relevant data and display them in proper fashion.

    Subband coding of speech signal using scilab
    (International Journal of Electronics & Communication, 2014-05) Ravindra, Chaya; Khatik, Ramjan; Pathan, Siraj; Nawaz, Banda
    Subband coding decompose the input signal into different frequency bands .After the input is decomposed to its constituents, we can use the coding technique best suited to each constituent to improve the compression performance. Decompose a signal into components by applying frequency-selective filtering. Then select the best coding technique that best suits each component (subjectively and objectively). Subband coding applications are Speech coding ITU-T G.722 Encode high-quality speech at 64/56/48 kbps. Interest in signal processing long predates computers. As long as people have tried to send or receive information through electronic media, such as telegraphs, telephones, television, radar, etc., there has been the realization that these signals may be affected by the system used to acquire, transmit, or process them. Sometimes these systems are imperfect and introduce noise, distortion, or other artifacts. Understanding the effects these systems have and finding ways to correct them is the foundation of signal processing . This paper depicts analysis side of the system implemented using freeware language SCILAB. The synthesis side includes speech production The digital filters have been implemented for extraction feature .The signal processing application of SCILAB has become boon.
