    Good Online/Books to learn DSP for work?

    I have already studied DSP in my Master degree. However, As I am starting a job where a good percentage of my work is to design DIGITAL FILTERs, I still feel like I don't know that much on DSP and I really need to become a good engineer in this topic and take it to another level rather than...

    HW Interface to detect Radio Control Receiver PWM signal

    I am using an Arduino Pro Mini to detect a PWM signal from a radio control receiver. The input pin on the Arduino is supposed to be limited to 20mA current with a max current of 40mA. I plan on using a 220 ohm resistor in the circuit. Do I need a .1uF cap to ground (and what kind of cap)...

    Extracting filter coefficients from fdatool IIR filter object

    Hi everyone, I have designed an IRR filter in fdatool but since I can't export the coefficients as a vector into the workspace, I exported the filter as an object. The problem is that when I open the object, I have 3 arrays stored in it (ScaleValues, States and sosMatrix). Please, could someone...
