Analog Lab 6

LOW PASS FILTER

Corner Frequency(min)= 1/(2(pi)(10)(.000001))

=15.915 [Hz]

Corner Frequency(max)= (2(pi)(10000)(.000001))

=15915.494 [Hz]

Range (approx.) = 15[Hz] – 15[kHz]

HIGH PASS FILTER (right circuit), TOGGLE-ABLE HIGH & LOW PASS FILTERS

Corner Frequency(min)= 1/(2(pi)(10)(.000001))

=15.915 [Hz]

Corner Frequency(max)= (2(pi)(10000)(.000001))

=15915.494 [Hz]

Range (approx.) = 15[Hz] – 15[kHz]

Part 4: You can create a steeper filter by putting 2 equivalent filters in series!

Part 5: idea for final project: make a “bass boost” box that splits an analog signal, then low passes one, then adds them again.

Complicated idea for final project: make a “slow and reverb” box, following the trend of doing slowed and reverb-ed songs on youtube.

Another Idea: make a “noise cancelling” box for headphones, that mic’s the room sound, inverts the signal, and adds it to the audio.

It would be cool to know how manipulatable drum machines work.
