Let's Play 'Syphon Filter' - OUTDATED -

NOTICE: These videos are out of date, as they don't reflect what I wanted to originally do with the Let's Plays and also have various technical issues, which I feel don't fit certain desired standards I have set. You can still view them by clicking the links from this post, but I made the videos "Unlisted" on YouTube. There will be a revised and decidedly improved playthough done at some point in the future.

I am uploading a series of videos about the incredible PS1 stealth shooter classic Syphon Filter, developed by Eidetic (now Bend Studio) and published by 989 Studios (a division of Sony Computer Entertainment), a video game that is so fond to me.

Butterworth, Sallen-Key & Chebyshev Filter Analysis, Design and Synthesis

I separate the implementation in several parts as outlined below.

Part A.
A1. Design a normalized low-pass filter with Butterworth response, cutoff rate equal to 18dB/octave and maximum allowed gain deviation in the pass region equal to amax = 1.5 dB.
A2. Implement the normalized filter by connecting in cascade multiple sections. All capacitors must be identical. For the implementation of the second section, use a Sallen-Key filter with identical resistors and identical capacitors (Design II).
A3. Depict the logarithmic gain curve as calculated from the transfer function of the design along with the transfer function of the circuit.
A4. Denormalize the circuit such that the cutoff frequency become fc = 1.6 kHz and the resisters be at their normal values with dimensions. Sketch the logarithmic gain curve of the denormalized circuit given frequency f (logarithmic axis)....
