### Joe West (@Joe_West)

Semi-retired, now doing part-time consulting while enjoying my grand kids. EE by formal training, have done work in optics/lasers, digital servo-loops, phase-locked loops, RF/microwaves, switch-mode power conversion, the list goes on. It's all been (and continues to be) fun.

## Re: Some practicalities with implementing DSP and Digital Control

Not specifically mentioned is that if you are doing something that involves a derivative (time-rate-of-change), having jitter in your sampling interval can result...

## Re: Sampling frequency of slow phenomena to obtain PSDs

I don't see anything at the 12 Hz noted by kjh. As I read the frequency scale, the first "peak" is at 1.2 Hz. (The center of the plot is at 10^0 Hz, which is to...

## Re: choose the antialiasing filter

The 500ns settling time of the ADC is what is required for full 12-bits of resolution to a full-range step input. (Resolution doesn't address things like ADC linearity...

## Re: choose the antialiasing filter

You state that you want 40db of attenuation at half the sampling rate. That is one part in 100 of voltage. Yet you also state that you want 10-bits of resolution....

## Re: Carrier Recovery, Frequency and Phase in (CP)FSK

I do agree that a more complete description of the setup would be very helpful.But note that atorres stated in his initial posting that this was an _acoustic_ channel...

## Re: Generating Bandlimited Noise

Dres wrote:We cannot sample infinite bandwidth signals. We can only sample a bandwidth up to the Nyquist Frequency = Fs/2This is correct only if the input signal...

## Re: Who clones DSP56362?

The DSP56362UM.pdf "users manual" says (in part)---3.1.1.2 Program ROMThe program ROM contains customer-supplied code. For further information on supplying code...

## Re: Is anyone familiar with the mathematics / theory behind Convolution Reverb, especially in regards to frequency?

Very slight "nit-pick" on Tim Wescott's response where he says "surprised, if there's not also a frequency-dependent directional characteristic; i.e., a given surface...

## Re: Power Measurement of Complex Signal

You need to understand that dB is always the base-10 log of a _power_ ratio. dB = 10*log(P2/P1). This is commonly bastardized to be 20*log(V2/V1) which is correct...

## Re: Tuning PID controllers

While I strongly agree with your "when it's good enough, STOP!" comment, my own preference for which order to adjust things in is different from yours. I'm curious...
