A: What is the difference between emitter and collector of a transistor? A bipolar junction transistor can be used as an amplifier, in which case some parameters of interest are $\alpha$ (the common-base current gain, equal to $IC/IE$) and $\beta$ (the common-emitter current gain, equal to $IC/IB$). (Here, $IC$, $IB$, and $IE$ are the currents at the collector, base, and... (more) |

A: Division of binary numbers logic circuit You're thinking of a digital comparator, "a hardware electronic device that takes two numbers as input in binary form and determines whether one number is greater than, less than or equal to the other number." (more) |

Digital circuit that squares a 4-bit input A few decades ago, I found a digital circuit that squares a 4-bit input in an old textbook (perhaps 1970s or 1980s). (The figure below is not the original. It differs from the original in that it has been rotated 90 degrees. Also the original figure had an error in the circuit diagram that has been... (more) |
