- 14. Advantages of Digital System over Analog System • Noise Immunity • Less use of Bandwidth • Encryption (At the transmission end we encrypt the data , only intended receiver can only decode by using proper key) • Efficiency is higher for long distance transmission. 14Zohaibhasankhan@gmail.com
- 16. Disadvantages of Digital System over Analog System • Accuracy is Poor (by using one switch we can implement two level High or Low) • To increase the accuracy we have to increase the number of levels , so that resolution increase and so the accuracy (increase the number of switch to increase accuracy) • Example Take a Class • All Real life signals are analog. 16Zohaibhasankhan@gmail.com

- 82. Zohaibhasankhan@gmail.com 82 One’s complement and two’s complement are two important binary concepts. Two’s complement is especially important because it allows us to represent signed numbers in binary, and one’s complement is the interim step to finding the two’s complement. Two’s complement also provides an easier way to subtract numbers using addition instead of using the longer, more involving subtraction method
- 111. Hamming codes Zohaibhasankhan@gmail.com 111 Hamming codes are a family of linear error-correcting codes. Hamming codes can detect up to two-bit errors or correct one-bit errors without detection of uncorrected errors. By contrast, the simple parity code cannot correct errors, and can detect only an odd number of bits in error. Named after: Richard W. Hamming
