Calibration of MEMS Microphone with Reference Microphone in Acoustic Box: Seeking Guidance
Started by 2 years ago●4 replies●latest reply 2 years ago●301 viewsHello everyone, I am currently involved in a project where I'm using two distinct types of microphones connected to an Audio Precision system, comprising an APx525...
Matlab waveform generation with added AWGN for Deep learning classification.
Started by 2 years ago●2 replies●latest reply 2 years ago●219 viewsHello,I am generating WLAN 802.11n/ac waveforms with 4 different modulation schemes (BPSK, QPSK, 16-QAM, 256-QAM) and feed the I/Q data into my Deep learning model...
Hello,As far as I understand the purpuse of a Farrow filter is to interpolate samples at a fractional ratio.For example: we have an ADC sampling at 41 MS/S and we...
Why is it said to be alias free in such a multirate system?

Hi guys, I took a look to"A beginner's guide to Cascaded Integrator-Comb (CIC) filters"and I am confused about registers width:register bit widths = 12+⌈3⋅log2(8)⌉=12+3⋅3=21bits ...
I want to try Acoutic Modems in Matlab and working with actual speaker and mike for transmission.I have designed 8 psk modem and another OFDM version QPSK Modem.Is...
Hi Sir,I want to use sigma-delta modulator and FPGA to implement digital power control, and I am studying the Understanding Digital Signal Processing CH13.24, and...
