What is the difference between a digital storage oscilloscope (DSO) and a cathode-ray oscilloscope (CRO)?
The answer is too simple Digital Storage Oscilloscope is one of the type of Oscilloscope. There are mainly 5 different types of scopes Analog Scope,Digital Storage Oscilloscope,Mixed Signal Scope ,Mixed Domain Scope,PC Based Scope.Analog Oscilloscope : Is the first product and the signal is captured and displayed directly on Cathode Ray and all signal processing is Analog in nature.http://www.scientechworld.com/pd...Digital Storage Oscilloscope : Signal is captured and then converted into Digital Data by high speed A/D converter and stored in memory and finally data is been read from memory and displayed either on LCD/TFT Display. It has many advantages that user can add PC Interface, Signal can be saved and recalled in external memory, many mathematical and logical operations can be done on the observed signal and many more.http://www.scientechworld.com/pd...Mixed Signal DSO : We can say the next version of scope , it has capability to see Analog and Digital Channels simultaneously. Very useful while working in the field of Embedded Systems.http://www.scientechworld.com/pd...Mixed Domain Scope : It is a combination of TIME & FREQUENCY Domain measurement in time correlation.PC Based Scope : Getting popular these days as they are compact , USB Driven , can be carried on filed for measurements. As it gets easily connected with PC, Laptop,Tablet and signal is observed on it. Technology has moved one step ahead and and now PC Based scopes are integrated with Power Supply,DMM,Logic Analyzer,Spectrum etc… and named as Complete Lab or DesignLab.DesignLab 3rd Generation | 3rd Generation
Will good piano software sound better than a good digital piano?
Both live and in the studio, I have found that most digital pianos at the lower and mid price ranges are lacking in one way or another. They’ll have one or more of the faults listed here:Poor keyboard touchPoor response to the keyboard touch - either goes from pp (quiet) to ff (very loud) with very little difference in touch, or requires bashing the hell out of it to get any kind of ff at all.Poor built-in speakers that are too harsh or too dull or too tinnyPoor sample quality - or sampled from a poor pianoUneven sound and/or odd changes in tone between adjacent notesToo quiet because the built in amplifier is weedyWhat you get from a good piano plugin on a computer is usually far better, provided you have decent amplification and speakers.Assuming you had a budget of less than 2500 UK pounds, you wouldn’t get a digital piano that really avoids all those faults. I’d do this:Go to eBay and get a secondhand Macbook with 8Gb RAM. (About 400 EURO)Buy the Pianoteq Stage plugin (99 EURO)Get a pair of decent active studio monitors (About 290 EURO)Get a Studiologic Studio 88 keyboard controller (about 400 EURO)Get a pair of Sustain pedals and a stand (about 60 EURO)Total : about 1250 EURO, or £1075, or $1380 at exchange rates as I write.It’ll sound and feel awesome. I know, it’s what I use live and in the studio now.For that money, any digital piano you might buy will be quite horrible unless you by some miracle get a really amazing below-trade-price deal on a new one.It won’t look as pretty, but if you want good touch and sound, it’s better. If you want you can even mount the Macbook on the keyboard - hey make a magnetic stand that fits right on - I use it live. It’s about £60, 70 EURO, or $80 though.
Can people distinguish between analog synthesizers and digital "analog-modeling" software synthesizers in double-blind listening tests?
I think we've reached a point where with a well-designed analog modeling synth in the hands of a skilled programmer developing the "digital duplicate" timbre that even the most ear-trained synth professional would not want to bet his or her paycheck on their ability to discriminate between the duplicate and the original.Remember that when we're talking about analog modeling, we're also talking about hardware synths. So, this would include the Access Virus, The Nord Lead, the The King Korg (and the Korg analog modeling legacy going back to the MS2000), and so on. Even purists agree that, for example, it's hard as hell to tell where an Access Virus TI2 analog timbre stops and an old school miniMoog starts. With software vsti's and the like, there are some equally great analog modelers provided that they are played through a high quality D/A converter. In short, this means having a professional audio interface and not the single sound chip soldered to your laptop's motherboard. Listen to Sylenth, Z3TA2+, Massive, Spire, Gladiator2, or even the Arturia reproductions and on a reference-flat audio system, I think Bob Moog himself (RIP, Bob) would laugh and declare that hardware Moogs are history. I'll get a lot of flack from purists who will say I'm an idiot (I own half a dozen classic analog synths), or the hardware crowd decrying soft synths to be "tinny sounding junk" (I own three Viruses, a Nord Lead 2, a JP-8000, an MS2000 and a Microkorg, an Akai MiniAK, four Novation analog modelers,a Blofeld, an Alesis Ion, and a Venom) but when you look at videos of producers (AVB, Markus Schulz, Paul Van Dyk, etc.) in arguably the largest genre requiring the use of analog synths (Trance) and you see ONLY Sylenth, Omnisphere, Nexus2 and the like, you begin to realize that analog modelers are big boys now...as are vsti's.
