Typical techwriter gobbelygook. yes, the clock is fed to a flip flop, yes, ANY clocked flip-flop will "divide by 2". Erik That's not strictly true on the face of it. At this moment I can't think of a clocked flipflop that can't be made to divide by two, but none of them do that on their own. A 'D' type must have its output inverted and fed back to its 'D' input. A 'T' flipflop (e.g. a JK with both J and K tied together) will toggle (divide by two) whenever the JK inputs (='T') are true. That's not exactly consisten with the quoted remark. A clocked R-S (which I've only seen it textbooks, never in physical form) can probably be induced to divide by two, though I'm not sure how or why one would do that. I mention this only because there are some readers who code in 'C' and have never actually seen physical hardware. More correct would be, "ANY clocked flip-flop CAN divide by 2." RE |
