What is smallest addressable value in an octal number called?
In a binary number, the smallest addressable value is called as a bit.
In a decimal number, the smallest addressable value is called as a digit.
In an octal number, what is the smallest addressable value called as?

Confused with the effect number of decimals at the output of transducer
There is an ultrasonic device which measures and outputs both wind speed and direction and has a very long manual. But to keep it short and summarize, the accuracy and the resolution for the wind direction is given in the following table:
As…

How do computers understand decimal numbers?
Computers calculate numbers in 0s and 1s. A bit can be either but not in between. So if you enter 3/2 into a calculator, it should return either 1 or 2, right? Wrong! It gives you 1.5, the correct answer. Even on problems with more complexity, the…

Can BCD and binary multipliers share circuitry?
Suppose you are implementing a BCD multiplier. Google says there are reasonably efficient known circuits for this. Say 8x8 -> 16 digits, and trying for a reasonable compromise between speed and number of logic gates.
And suppose the CPU in which…

Decimal addition using a different BCD WEIGHTED CODING
The problem that I'm having trouble in understanding is how the addition of two decimal numbers such as 17 + 4 can be represented using the weighted BCD CODE, [7 4 -2 -1] and binary addition techniques.
From what I have understood when doing BCD…

VHDL initialize vector using readable integers not long binary string
So I am only starting out my VHDL journey. One thing I am finding a bit of a nuisance is the following format:
signal sig_A : unsigned (3 downto 0) := "0101";
being that "0101" is just a string which somewhere down the line gets converted to bits.…

The minimum (negative) value of the exponent in decimal
I am learning computer architecture and organization. I am stuck in the following question. Can someone please help me?
For a floating-point representation with 35 bits in the mantissa and 15 bits in the exponent, the number of significant digits…

32 bit to 7 segment display (FPGA)
After some research, I think I have quite a problem on my hands.
I have a project on an FPGA where I store a 32 bit binary value in a 32 bit memory register. The stored value ranges from 0 to 4000 in decimal.
I would like to display this decimal…

How many logic gates does it take to implement base-100 addition?
I'm curious about the trade-offs that have been made in implementing different kinds of arithmetic in different models of computers, to which I'm trying to understand what the costs of various options would be.
Say you want to implement base-100,…

Is it possible to make a circuit that can convert binary to decimal?
I know that computers use binary to calculate instructions and perform tasks. But essentially no one I know can convert binary to decimal. I am working on a calculator project currently, and the problem I have is converting binary to decimal for…
