Design ADC & DAC Within the system there are combinations of analogue and digital variables within the system. The purpose of the ADC is to convert analogue signals into digital ones within the system before it can be manipulated by the FPGA. The ADC takes the analogue information provided by the PGA and converts it into digital to be multiplied with the blood flow simulation signal by the FPGA. In order for the ADC input and output to communicate between the PGA and FPGA effectively important

CHAPTER 2 BINARY CODE 2.1 History of Binary Code: Binary numbers were first described in Chandashutram written by Pingala around 300 B.C. Binary Code was first introduced by the English mathematician and philosopher Eugene Paul Curtis during the 17th century. Curtis was trying to find a system that converts logic’s verbal statements into a pure mathematical one. After his ideas were ignored‚ he came across a classic Chinese text called I Ching or Book of Changes‚ which used a type of binary code. The

0.1 to 255.254 C 192.0 to 254.255.255 1 to 254 Any address starting with a 127 is a loop-back address and only used for addressing the host. All binary 1s at the host number means a broadcast to all hosts on that network. Ex. 198.60.81.255 is a broadcast over 198.60.81 network. If all binary 0s at the host number‚ it means “this host”. If all binary 0s at the network address‚ it means “this net”. Basic IP addressing and ARP [pic] Host 1 wants to send

Ghate RAIT Navi-Mumbai snghate23@gmail. com ABSTRACT The primary advantage of XS-3 coding over BCD coding is that a decimal number can be nines ’ complemented (for subtraction) as easily as a binary number can be ones ’ complemented ; just invert all bits. In addition‚ when the sum of two XS-3 digits is greater than 9‚ the carry bit of a four bit adder will be set high. This works because‚ when adding two numbers that are greater or equal to
