If you don't know what you'd even use it for I'd recommend just getting one of those $50-$100 chinese DDS-based generators, they look like toys but actually are not bad at their job and it might be enough for what you do Other option I'd suggest looking into is something like Analog Discovery 2 (it has education discount too). DIGITAL COMPUTER ELECTRONICS MALVINO EEVBLOG GENERATORThe more important question is "what gear you actually have and what would adding a signal generator to it allow you to do?". DIGITAL COMPUTER ELECTRONICS MALVINO EEVBLOG SOFTWAREDownload the Waveforms software and run some of the demos, see what you think. It will produce a Bode' plot of a filter with no external gadgetry. Of course, the Analog Discovery 2 does a better job within it's range but adding harmonics isn't one of its capabilities. Transistor amplifiers, op amp circuits, filters, etc. It is absolutely true that I bought the 2082 for the Heart project but it is pretty nice to have a real signal generator when testing analog kinds of circuits. My interest is digital and I can generate just about anything I need. I have only had crappy signal generators for decades. Probably the best tool for digital work is the new Digilent Digital Discovery This thing will Do Everything But Eat (DEBE device) and it's fast! In a more analog environment, the Analog Discovery 2 is magnificent. Similarly, it's easy to implement SPI or I2C with an Arduino and only slightly more difficult with an FPGA (actually, SPI is easy, it's I2C that's a PITA). It's pretty easy to create a 100 MHz chain of logic signals with an FPGA. So, build the digital signals with an Arduino or an FPGA (depending on speed). But all of that stuff is analog and you're interested in digital. DIGITAL COMPUTER ELECTRONICS MALVINO EEVBLOG PLUSPlus it has a lot of built-in signals, RTFM. In other words, it will build some very sophisticated signals. I think the 2082 will go up to 8 harmonics. Notice also the ability of each channel to stack in harmonics at phase shifts relative to the dialed in fundamental. Notice that the project requires an X and Y signal output to the scope. I bought the Siglent SDG 2082X so I could duplicate the Valentine Day heart here: 's-day-activity-for-your-scope-and-function-generator/msg1136847/#msg1136847 Read the specs carefully! It puts out 80 MHz sine wave but only 25 MHz square wave. I've heard SDG1032X can be improved to SDG1062X in a similar way. SDG2042X is better signal quality as mentioned and some have found ways to improve them to SDG2122X and you can read about that in the SDG2042X thread. A SDG1032X is a good choice and has plenty of capability to grow into. You will start out thinking one channel is enough and for a while it is, but as knowledge and needs develop it won't be long until you want/need more. I hankered for a function gen for years and the first I had was a Philips 2 MHz single channel job that now would be the last thing I'd use. Sure, with a few 4000 logic IC's you can achieve the same result be it's easier to have it built into the AWG. There's a # of features in the Siglent's were you can tie/link outputs in configurations that help. I have on occasion used a second channel in logic design checks when you need inputs in different states and different levels. "About this title" may belong to another edition of this title.For one, you can use the second or first as a low power DC supply which for breadboard use might be all you need. An Instructor’s Guide containing answers to chapter questions and experiment results is also offered. It also includes a student version of the TASM cross-assembler software program.Įxperiments for Digital Computer Electronics, prepared expressly for this Third Edition, contains hardware and software experiments that allow students to expand upon the topics covered in the text through hands-on exercises. This edition correlates closely with popular chip trainers and includes added coverage of the Intel 8088 16-bit microprocessors. Instructors can focus on just one of these popular microprocessors, or include the features of others. The text then relates these fundamentals to three real-world examples: Intel’s 8085, Motorola’s 6800, and the 6502 chip used by Apple Computers. Striking an ideally balanced approach, this text introduces students to microprocessor fundamentals by using a pedagogical SAP (Simple-As-Possible) model computer.
