    Why does not the make file or code compile correctly?

    I looked into example folder and compiled sample program sim.c. But the build ran into so many errors with missing dependencies and syntax errors. I was surprised because , the mushasi emulator is an established code and used in several projects. Perhaps I am doing something wrong. I did contact...

    Why does not the make file or code compile correctly?

    OK make is working fine. Now how do i start running the emulator?

    Why does not the make file or code compile correctly?

    Sorry for my ignorance, but how do I run make from Codeblocks?

    Here is the make file. Please suggest the workaround

    Why does not the make file or code compile correctly?

    As a hobby project, I am trying to run a legacy 68x emulator using codeblocks gcc. The link is https://github.com/kstenerud/Musashi. I do not understand why the Make file runs into errors. There are also errors in the code. I guess that all the codes that exist in the repository are free from...

    Analog pulse modulation-Working circuit

    Many of the links provided by google does not have model/circuit which actually works. I am just looking for that one. I understand the theory.

    Analog pulse modulation-Working circuit

    It is only for academic experiments so specifications does not matter. But I need working circuit with values of passives

    Analog pulse modulation-Working circuit

    I have searched a lot but unable to find working circuit which illustrates flat top, single polarity pulse amplitude modulation. Help required.

    extracting carrier signal

    A very silly proposal. What if I divide the modulated signal by the message ( If I have one). Will I not get back the carrier.

    extracting carrier signal

    I was not clear with the intention until discussed with the researcher in detail. But you had indicated earlier that bandpass filter will not work effectively for AM signal and secondly you are suggesting a XOR detector. Little bit on confusing. Could you please explain with the implementation...

    extracting carrier signal

    Finally I got to the root. Originally this problem was shared to me by a young researcher and wanted all analog solution. After a detailed discussion, he came up with the patent document that specified this particular problem and possible solution. I have attached the document. Please refer to...

    extracting carrier signal

    My exact problem is to extract the value of Phi. And perhaps I am trying to evaluate several options after reading posts here. Therefore my primary question was to extract carrier thinking that it could be one of the plausible solution. I was also wondering about the response time of DSB-SC...

    extracting carrier signal

    Can you please elaborate your point mentioned in #22. I am not quite clear. Also I see that square wave generated from comparator is symmetrical whereas the source is not (discontinuity at zero crossings). Please clarify.

    extracting carrier signal

    Intention is to recover the value of Phi. The possible method is to compare a reference 1 KHz signal to the cos(phi-w2*t) signal and infer the value of phi implicitly. Since carrier recovery was not so easy as mentioned in previous posts (for AM signal), I preferred some simple solution such as...
