@SRobertJames It looks like TAMB and TJ are outputs, not inputs. However, there doesn't seem to be documentation on them, either. TAMB, for example, seems to be a 1k resistor in parallel with a 1nF...

@SRobertJames If you want to put to bed these questions about your schematic, post up the netlist in your question. That will resolve all questions like this.

@Graupe Then just use a latching relay. A pulse from a transmitter to the receiver and a simple circuit between receiver and relay is all. So I think. You don't seem to care that the receiver will...

If you have your answer, you may wish to select one. Or write your own and select it! Either way works! Or do you still have some unanswered details?

Curggles, you have some answers below. You've said nothing since. Is there something you still need to work out? Or are one of the answers below good enough? Just curious.

Besides, you've made it into a competition for the least number of components. Unless there were good motivation given, I'd want to sit things out for that reason alone.

For a pure sine/cosine wave your calculation relating 2 Vpp to 10 dBm into 50 Ohm load is correct. But what's the question? Are you planning something where you never want to see any clipping, ever?...

@OwenM Edited to correct my mistake about numbering the parts. But yes, this is a "simple" divider problem. If you want to get a feel for it without capacitors and inductors, just replace all the C...

Kyle, redesign the circuit to make better use of the 9 V supply. This means using the resistor divider at the (+) input of the opamp, for example. And not to create a ground return. Then just connect...

@DaveTweed I agree. Except that I wouldn't go so far as to say "no way." I've put them on bakelite perfboard and even drilled holes in the perfboard so I could screw them down. So they can be used...

The "design" looks a bit lacking. But the questioner does seem to have already stripped off A0 and A1 from the PC register (looking at the splitter there) and to only be using 6 bits (A7 downto A2) for...

Which MIPS? R2000? R3000? R4000? etc. Also, why no pipeline? Not that I can't come up with a single clock implementation. But why no pipeline (originally 5 stage for R2000, memory serving.) Also, it...
