How can we realize a second order digital FIR filter without using a microcontroller. What assumptions would be taken?
I've come across a few examples that the scaling factor T in the eqn below can be arbitrarily chosen as unity. How is that possible? doesn't T have something to do with the Nyquist sampling rate? ...
I want to build a simple and ultra low cost circuit that can detect a timed (let's say 200ms) pulse of a single sine frequency - say,15KHz. Amplitude will be around AC ~1Vp-p. Detection will give a ...
Im trying to implement a simple first order IIR filter on a MCU (PIC24FJ32GA002), without success until now. The filter is a DC tracking filter (low pass filter) whose purpose is to track DC component ...
This is in regards to digital communications. I have a link I've set up using GNURadio that's sending BPSK modulated data through water via a LED. I can control the roll-off factor, $\beta$, of the ...
