While decoding the cyclic code, if the received code word is similar as transmitted code word, then r(x) mod g(x) is equal to . . . . . . . . A video transmission system transmits 625 picture frames per second. Each frame consists of a 400 × 400 pixel grid with 64 intensity levels per pixel. The data rate of the system is The n-p-n transistor made of silicon has a DC base bias voltage 15 V and an input base resistor 150 KΩ. Then value of the base current into the transistor is Leakage current approximately doubles for every 10°C increase in temperature of a silicon transistor. If a silicon transistor has I CBO = 1000 nA at 30°C, what is its leakage current at 90°C? Which one of the following is used as the interface chip for data transmission between 8086 and a 16-bit ADC?
