Questions tagged [dsp]

Questions about digital signal processing, whether of RF, audio, or digital signals. For RF, consider [software-defined-radio].

Use this tag when the topic includes Digital Signal Processing. This can be either RF signals or audio signals, or perhaps post-processing like decoding of protocols.

is a perfect example of DSP-based radio. Similarly, recording of signals for later processing (like manipulating satellite imagery to assign false colors and the like) could be considered to fall under this category.

What exactly is the IF output on radios?

My Kenwood TH-D74 and ICom 7300 both have the ability to output IF instead AF. Is this IQ signal at 12ksps, meaning 12kHz of bandwidth, or something else? What are some projects that can be done with these? Seems most digital modes work just fine…

Will the quantization noise be increased if the step level is increased?

Will the quantization noise be increased if the step level is increased? I was wondering about the relationship between the step size of the quantizer and quantization noise,
