What are the benefits and negatives between Analog and Ditigal voice transmitters, and receivers?

Question

Which holds the advantages in clarity, range interference,
and price? This is in regards to HF and VFH frequencies.

Answer 1

Digital will always have a better signal to noise ratio, meaning it can hear perfectly fine at a lower siganl level than analog. The problem is bandwidth. The wider the range of freqeuncies and sampling rates desired, the more complex the digital mode, and higher the bandwidth. Digital modes break up the speech into tiny bits (samples), encodes the data, sends it and then decodes it. The nice thing about digital is that it will always be near perfect on the receiving end, or nothing at all. Digital is more expensive but easier to encrypt. Digital also has a delay. It takes time to process the audio, send it and deprocess it. This will cause a slight delay.

Analog has a worse signal to noise ratio. You are sending at an near infinite sampling rate though. Bandwidth is directly proportional to the audio bandwidth. Analog is cheaper, but difficult to encrypt. There is no delay.
