Quick questions before learning a new tool and starting development with ADAU1787 eval board using Sigma Studio (never used this tool before).
I want to set up a 1-channel mono (microphone) - input, and 2 channel quadrature output (for a radio communication product development). The frequency range of the mono-input (and output) is voice band: 300 Hz - 3600Hz.
The 2-channel output audio signal (quadrature I&Q) will be achieved by loading Hilbert FIR filter coefficients externally on boot; unique set of coefficients for the I and Q channels respectively.
I assume a Hilbert transform is not available in Sigma Studio. I can generate my own Hilbert transform coefficients (not Matlab).
1. Assuming this is doable but would appreciate someone directing me to the appropriate tools inside Sigma Studio to allow file imports.
2. Alternatively, can C-scripts be used inside Sigma studio to generate the coefficients upon boot?
I would appreciate some advice before diving in.
Please advise. Thank you
