The fist step in the design is to derive the truth table of the combinational circuit. The minimum size ROM needed must have three inputs and four outputs. It is difficult to show the implementation of PAL in the above connected and disconnected fuse form.
Example 9. Also write the PAL programming table. The k-maps for the above expressions, their minimization and the minimal expressions obtained from them are shown in figure. The fuse map for the PAL as specified in the programming table is shown in fig. The output voltage cannot exceed the positive and negative saturation voltages. Thus, curve is called an ideal voltage transfer curve, ideal because output offset voltage is assumed to be zero. OPen-Loop Op-amp Configuration In the case of amplifiers, the term open-loop indicates that no connection exists beteen input and output terminals of any type.
In open-loop configuration the op-amp functions as a high gain amplifier. The Differential Amplifier Fig. Since, the op-amp amplifiers the difference the batween the two input signals, this configuration is called the differential amplifier. The Inverting Amplifier If the input is applied to only inverting terminal and non-inverting terminal is grounded then it is called inverting amplifier.
The negative sign indicates that the output voltage is out of phase w. The Non-Inverting Amplifier In this configuration, the input voltage is applied to non-inverting terminals and inverting terminal is ground as shown in fig. In all there configurations, any input signal slightly greater than zero drive the output to saturation level.

Sorry for my vagueness though. After one of the shifts, there are two BCD digits suddenly requiring -3 at the same time. Show 12 more comments. Chromatix Chromatix 3 3 silver badges 6 6 bronze badges.
Add a comment. I cannot use a look up table because 16 bits have 64K possible combinations, which would take a lot of time to build. How was I supposed to know? I joined yesterday and this was my first question, sorry for vagueness.
Just multiply each digit by a power of 10 and add them up. Easy to do in the hardware. The multiplication can be done by small LUTs. Are the bcd digits coming in serially, parallel? What about the bits of the output? Show 8 more comments. Peter Green Peter Green Though I appreciate Tom Carpenter's solution a bit more, this one is also good for a sequential implementation.
You need something to end work on one number and start work on the next though. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password. Post as a guest Name. Email Required, but never shown.
