Ghani Lawal- Added results of frequency test to Frequency Information excel file
- ***When headphones are connect to the Y-splitter while the oscilloscope is connect to the other port of the Y-splitter the max voltage of the waveform is reduced, interestingly enough, when I'm listening with headphones and have the oscilloscope connect or disconnected to the second port of the y-splitter it doesn't appear to affect the audio volume
- Simulated op-amp LED Ladder Display
- Seriously considering using the LM3915 Dot/Bar Display Driver IC instead of building my own LED display; less discrete components will be needed and will therefore save space, also can drive up to 10 LEDs
- When I want to build a comparator circuit with LTSpice, use op-amp LT001
- Am now using a 6th order Butterworth filter to isolate the Sub-Bass frequency spectrum
- For the Bass Filter, I entered in parameters: Center Frequency - 155Hz and Passband - 190Hz, the filter-wizard returned a 6th order Butterworth filter centered a 182.5 Hz with a Passband of 190, in order to get the passband that I desired I had to change the Center Frequency to 122 Hz. ***Will have to make similar fixes to the remaining filters
Hardware Test, LM3915, Comparator LT001 and Filter Fixing
A project log for Music Spectrum and dB Visualizer
Receive input from a 3.5mm jack, divides the music into 7 frequency bands, shows the loudness of each frequency band in DB using LEDS.
