Hey there....I have put up this post before but never got any replies that were relevant and it was and still is important hence
urgent
The diagram i am refering is not figure 5 on page 5 but rather to schematic 5 in appendix C of the document. The thing is i dont have a background in electronics so the explanations in the document are too brief for me.
Refering to schematic 5 in appendix C, i have the following questions?
1. How does one go about designing this circuit ie what are the formulaes that are used, how do you know where to place each component, how do you determine the values of the various components.
2. I know what the basic purpose of the amplifiers are for but how do they actually function?
3. what does the envelope detector do?
4. What is the purpose of the 5 not gates in this circuit?
5. What are the functions of the following components: C19,R21,C27,D9?
6. what would the signal waves look at at these various points of this circuit: at the input or carrierdata, after the high pass filter, after the tuned amp, after C27, after the untuned amp, after D9, after the envelope detector but before U2:E and after U2:E
The following are my questions regarding this circuit. Please help.
