'at the expense of precision'... How so? Because the numerical value of the least significant bit of the mantissa i.e. its meaning if you like changes depending on the value of the exponent. For example, if the exponent was 0, the least significant bit of the mantissa would have a numerical value ...

Floating point in computing terms is a means of increasing the range of numbers that can be expressed at the expense of precision. In essence, floating point quantities have so much dynamic range that it is very difficult to achieve overflow or "clipping" when performing maths operations with them ...

Yeah, I wondered about that, why do you think that chane? Because as I understand it SSDs are like flash drives in that once they write to a blank space they can't erase the data written there and rewrite to that exact same space again, like HDDs can do indefinitely. I don't think SSDs can't even ...

I may be able take a look at it for you. Where are you based?

This compressor is so obscure, almost nothing about it on the net, and not many have heard of it, but I’m constantly amazed at how good it is, you can get real attitude with it, or, what I use it for, exceptionally unobtrusive limiting, which is crazy considering, but it just does it, it's soft and ...

I'll never understand the rationale of manufacturers, no more than I know why toast always lands butter side down, but the SW1000XG was a cracking card, if only Yamaha had released 64bit drivers for the audio side of the card - a perfectly adequate MIDI synth and 12 channel audio all in the same ...

This will be too modern to have germanium transistors like the OC71. I'd imagine it will have a load of ordinary silicon transistors possibly in metal cans like BC109 etc, some, possibly many, TTL logic ICs and possibly the top octave generator and divider ICs used in many '70s electronic organs ...

Anyway, back to diagnosing the fault. Cm22 is a very likely candidate for the cause of the fault as it decouples the supply quoted as 11.4V that is applied to the first transistors Qm1 and Qm2 in both channels of the phono preamp. Other likely capacitors are Cm23 that decouples the 28V supply to ...

I've only heard an airing cupboard being referred to as a hot press in Ireland. I didn't know that term is also used in Manchester.

I find that storing each of my basses in their case / bag when not in use makes the strings last much longer than when an instrument is left on a stand in the open air.

I agree that it's a bad idea to re-use IDC connectors - I'm sure that you really don't want to take the whole thing apart again when they become unreliable.

voltage across c105 : volmeter dc 5.81v This looks a bit lower than I'd expect. What DC voltages do you measure across D40 (or C103, they should be the same thing) R235 R236 (R2 in your diagram) You say that you replaced Q42, what type of transistor did you replace it with? Did you replace Q41? If ...

That's because there is yet another standard that uses USB-C connectors namely DisplayPort 2.0 and upwards. This transports DisplayPort video data via USB-C cables - this is what your Steam Deck provides. This differs from Thunderbolt in that only either DisplayPort or USB are transported and not ...

When I bought a hub for my Steam Deck I was told that USB-C and Thunderbolt are the same thing. I'll admit I was confused, but the hub he sold me works, so... Recent Thunderbolt devices use USB-C connector but Thunderbolt is not USB, although, confusingly it's likely to be compatible. Yes that's ...

The Core i7 name was first used for the higher end of the Nehalem range of 45nm processors released at the end of 2008.

They're both RAM. An SD card is static RAM -- it keeps the data when the power is off, and RAM for a PC or Mac is dynamic RAM, or DRAM, which loses the data when the power is off. DRAM might be better called 'forgettory' than memory, as it needs refreshed constantly to remember the data. It is ...

Yes, a remote handset is a digital device and modern types are almost certain to contain a microcontroller running some software, but it doesn't necessarily follow that a remote is likely to fail. It is possible for such systems to be reliable and a remote handset being a very simple system helps ...

I'm not familiar with remote handsets for smart plugs, but the ubiquitous TV remote is, in effect, listening at all times. When no remote button is pressed, the remote's microcontroller will be in a very low power "sleep" mode where it is waiting for an interrupt from a button to wake it up, the IR ...

Perhaps, but your remote control handset is most definitely a digital system - it will probably contain a low power microcontroller of some description.

John

Anyway, what would be your thought regarding the whole CPU usage/DMA thing please? It's a topic thats really outside my area of competency I'm afraid. Hopefully someone who really knows this stuff can advise. USB host controllers (the part that is in the PC, Mac or whatever) have used DMA since the ...

Apparently Joe Zawinul had a similar issue with his ARP 2600 when he first got hold of one. I suppose that means I'm in good company

John

I did sort this out - it was due to user (me) error. I had the VCA initial gain set to a non-zero value such that there was some output at all times.

The Core-i9 has higher turbo speeds, more cache and higher maximum power consumption. Links to Core-i7 and Core-i9 details.
