Thanks for the suggestions!
I actually tried to use PSpice to simulate a simple circuit with transistors and diodes from 'Modern Electronic Circuits Reference Manual' but it didn't work. I wonder how practical such circuits (built with discrete transistors and diodes and R's and C's) would be...
I need a simple AGC circuit, either digital or analogue, consisting easy-to-find chips/components, with 50-60dB range. Frequency range is around 100kHz to 400kHz. Is there any already existing ones that I can grab and use? Thank you very much!
I have 2 questions about a straight cylindrical tube placed along x axis, terminated (not rigidly) at one end x=L. (So the acoustic impedance ZL at x=L should normally be a complex number.)
Question 1: I wonder if ZL should be different under 2 cases, (both assuming wavelength is much larger...
