The document discusses binary number conversion between decimal and binary representations. It provides two processes:
1) Decimal to binary conversion uses successive division, where the decimal number is divided by 2 and the remainders form the binary number bits.
2) Binary to decimal conversion uses weighted multiplication, where each bit of the binary number is multiplied by its place value and the products are summed to obtain the decimal number. Worked examples demonstrate converting specific values between decimal and binary.
Parity bits are used to detect single bit errors during data transmission. There are two common types of parity - even and odd. Even parity means the total number of 1s in the transmitted bits including the parity bit should be even. Odd parity means the total should be odd. The receiving device calculates parity and compares it to the received parity bit to check for errors. While parity can detect single bit errors, it cannot detect errors if an even number of bits are corrupted.
- Digital computers perform arithmetic operations like addition, subtraction, multiplication and division on binary numbers.
- Signed binary numbers use the most significant bit as the sign bit to represent positive and negative values. Common representations are sign-magnitude, one's complement, and two's complement.
- Subtraction is performed using the two's complement method by taking the two's complement of the subtrahend and adding it to the minuend. Overflow needs to be handled for accurate results.

Fixed-point and floating-point numbers can be represented in computers using binary numbers. Floating-point numbers represent numbers in scientific notation with a sign, mantissa, and exponent. In 8-bit floating point, numbers use 1 bit for sign, 3 bits for exponent, and 4 bits for mantissa, such as 0.001 x 21 = 2.25. Larger precision formats such as 32-bit and 64-bit floating point according to the IEEE standard use more bits for exponent and mantissa.
Wavelet packets provide an adaptive decomposition that overcomes limitations of the discrete wavelet transform (DWT). In wavelet packets, signal decomposition using high-pass and low-pass filters is applied recursively to both low-pass and high-pass outputs, allowing more flexible time-frequency analysis. This results in a redundant dictionary with increased flexibility but also higher computational costs. Pruning algorithms are used to select an optimal subset of bases for a given application based on cost functions related to properties like sparsity, entropy, or energy concentration.

The enhancement on a simple encoder circuit, in terms of handling all possible input combinations has lead to the development of special circuits known as Priority Encoders. These circuits facilitate in compressing several inputs into numerous small outputs. The quality feature of these encoders is encoding the inputs just to make sure that only highest order lines are encoded. The result or output of the priority encoder should be a binary representation of ordinal numbers articulated in BCD format. In addition, these also manage interrupt requests through high priority request. Whenever there is more than one active input at same time, then highest priority input will be given more preference. One can find priority encoders in standard or normal IC form such as TTL 74LS147 or TTL 74LS148. Basically, the former encodes 9 datelines to 4 lines as in (8-4-2-1) BCD. And the latter expresses 8 datelines to 3 lines as in 4-2-1 (octal) binary. In order to provide octal expansion with no requirement of external circuitry, one needs Cascading Circuitry.

Drowsiness is a critical factor impairing drivers’ performance in driving safely. There are several approaches in dealing with this issue based on human-machine interaction to detect drivers’ dozing off state, and then alert them to keep awake by sound or visual. These techniques fundamentally measure driver’s physical changes such as head angle, fatigue level and eyes states which are the indicators of drowsy state. However, they are limited in providing accurate and reliable results. Therefore, the project aims to achieve higher accuracy rate of drowsiness detection by using a very potential technology, electroencephalography (EEG) which is used widely in medical areas. Other than providing reliable result, the final product would bring more conveniences for customers with portability, easy-to-deploy and multi-device compatibility feature. In this project, its methodology first shows the strong correlation between drowsy state with brainwave frequency. Then a proposed system and testing plan are suggested based on the project objectives and available technologies. The final product is simply comprised of a hat with attached small electronic package used to record brainwave and a handheld device placing on dashboard of the car with an installed app. Finally, project management section will present in detail the human resources, scheduling, budget plan and risk analysis to show how it will be going to complete the project in six months.

Binary to hexadecimal breaks the binary number into groups of 4 bits and maps each group to a hexadecimal digit. Hexadecimal to binary does the reverse. Decimal to hexadecimal converts each decimal digit to its hexadecimal equivalent. Hexadecimal to decimal multiplies each digit by its place value and sums the results.
The document discusses different number systems including decimal, binary, octal, and hexadecimal. It provides the base, symbols used, whether it is used by humans or computers, and examples of converting between the different number systems. The key techniques described for converting between number systems include using place value, treating each digit as a group of bits, and using binary as an intermediate step. Powers of two are also discussed in the context of computing units like kilobytes and megabytes.
3. Decimal ‒to‒ Binary Conversion
The Process : Successive Division
a) Divide the Decimal Number by 2; the remainder is the LSB of
Binary Number .
b) If the quotation is zero, the conversion is complete; else repeat
step (a) using the quotation as the Decimal Number. The new
remainder is the next most significant bit of the Binary Number.
Example:
Convert the decimal number 610 into its binary equivalent.
3
2 6 r = 0 ← Least Significant Bit
1
2 3 r =1 ∴ 610 = 1102
0
2 1 r = 1 ← Most Significant Bit

10. Binary ‒to‒ Decimal Process
The Process : Weighted Multiplication
a) Multiply each bit of the Binary Number by it corresponding bit-
weighting factor (i.e. Bit-0→20=1; Bit-1→21=2; Bit-2→22=4; etc).
b) Sum up all the products in step (a) to get the Decimal Number.
Example:
Convert the decimal number 01102 into its decimal equivalent.

Binary Number System Digital Electronics 2.1 Introduction to AOI Logic Project Lead The Way, Inc. Copyright 2009
Introductory Slide / Overview of Presentation Explain that humans use base ten (or decimal), because we have ten fingers and that digital electronics uses base-two (binary) because it only understands two states; ON and OFF. For students to be able to analyze and design digital electronics, they need to be proficient at converting numbers between these two number systems. Base ten has ten unique symbols (0 – 9) while binary has two unique symbols (0 – 1). Any number can represent a base and the number of symbols it utilizes will always be that number. This is discussed further later in Unit 2. Binary Number System Digital Electronics 2.1 Introduction to AOI Logic Project Lead The Way, Inc. Copyright 2009
Review the DECIMAL-to-BINARY conversion process. Remind the students to subscript all numbers (i.e. Subscript 10 for decimal & subscript 2 for binary) A common mistake is inverting the LSB and MSB. The three-dot triangular symbol here stands for the word “therefore” and is used commonly among mathematics scholars.
