Cost of DSP In Other Consumer Items

High end digital HD TV - $2,000 Medical ultrasound - $20,000 MRI - $20,000,000

DSP isn't responsible for most of those costs.

Microdyne RCB-2000 telemetry reciever - $80,000

Is the cost of a $300 laptop different from the cost of a $300 bicycle?

Jerry

Only insofar as two years from now, replacing your $300 bicycle won't yet have crossed your mind.

You must be right. I still have the $96.50 bicycle I got in 1947.

Welcome to engineering! DSP is used when it is less costly than the alternatives; it is a cost savings to use a DSP filter rather than a tuned seven-pole wundernetwork. DSP is responsible, in a way, for the cost difference in HDTV using coupled vanadium tuning forks and HDTV with DSP, that actually does show up on the store shelves. Alas, there ISN"T any vanadium-tuning-fork price data easily available for this comparison.

The first derivative is certainly different.

How much does it weigh?

DSP must be commonplace in _some_ low end low priced consumer items, however well hidden.

Bret Cahill

A $60 cordless phone has at least two.

reminds me of last years tv from tour de france, two of the commentators rode up one of the mountain stages to show the route. one of the commentators has been in the Tour several times as a rider commented that it was harder than he remembered, but he also had about 20 more water bottles to drag up hill :)

Holy crap, there's Lasse again! And we were just talking about the black list, too... ;)

But isn't the on-topic question which one has more cost from DSP? ;)

Avinized? I'll have to remember that term.

The least expensive (GSM) mobile phone (whatever that is: can't be much, they give them away for "free") has about as much compute grunt as a Cray-1 (if you ignore the differerence in precision and size of the working data set).

My not all that expensive, but not bottom-of-the-line phone is at least

The least expensive MP3 player (within epsilon of $0) does a reasonable amount of DSP, although that's usually in an ASIC rather than a programmable processor, for battery-life reasons.

The only "expensive" consumer items that I can think of that have identifiable DSP functionality are A/V receivers, TVs and cars.

I used to hitch a folding two-wheel grocery wagon to my carrier and load it full. Saddlebags hanging from the carrier and a carton on top let me haul about 100 pounds of groceries up the hill home. (Before I had the bike with a gearshift, I snapped a chain going up that hill with only myself as load.) Weight matters when seconds do, otherwise, hardly at all.

I guess you missed him the other day. I'm ashamed to say that I neglected to greet him as you just did.
