Across
  1. 3. One in which amplitude varies in proportion to the sine function of an angle.
  2. 7. A piece of test equipment used to view and measure a variety of different waveforms.
  3. 8. The amount of time required for one complete cycle of a periodic event or waveform.
  4. 9. One style of integrated circuit package which has two rows of lead.
  5. 11. An algebraic expression made up of Boolean variables and operators, such as AND (-), OR (+), or NOT (-). Also referred to as Boolean function or a logic function.
  6. 12. The number of cycles per unit time of a periodic waveform.
  7. 15. The part of a pulse where the logic level is in transition from a HIGH to a LOW.
  8. 16. Fraction of the total period that a digital waveform is in the HIGH state. DC = th/T (often expressed as a percentage: %DC = th/Tx100%).
  9. 17. A diagram, similar to a schematic, showing the connection of logic gates.
  10. 18. The instantaneous voltage of a waveform. Often used to mean maximum amplitude, or peak voltage, or a pulse.

  1. 1. TTL-compatible IC that can be wired to operate in several different modes, such as a one-shot and an astable multivibrator.
  2. 2. Also called a NOT gate or an inverting buffer. A logic gate that changes its input logic level to the opposite state.
  3. 3. An almost instantaneous rise and decay of voltage or current in a periodic pattern with time and with a constant peak value.
  4. 4. Type of flip-flop in which the D (data) input is the synchronous input.
  5. 5. A technique of entering CPLD design information by using a CAD (computer aided design) tool to draw a logic circuit as a schematic. The schematic can then be interpreted by design software to generate programming information for the CPLD.
  6. 6. Delay from the time a signal is applied to the time when the output makes its change.
  7. 9. A series of logic 1s and 0s plotted as a function of time.
  8. 10. An electronic circuit having many components, such as transistors, diodes, resistors, and capacitors, in a single package.
  9. 13. A sequential circuit based on a latch whose output changes when its CLOCK input receives a pulse.
  10. 14. Unit of frequency. One hertz equals one cycle per second.
