Hali, köszi a videót, pont ezt kerestem. A storage depth:10kbit nem 10k minta, Ha azt feltételezzük hogy ez egy 8 bit-es cucc, akkor a legjobb esetben is 10k/8 vagyis maximum 1.25k mintapont lehet. De ennél valszeg kevesebb lesz. Főleg ha függ a memória attól is hogy melyik időalapban vagy. Sajnos eddig az Owon HDS széliánál láttam csak olyat hogy biztosra lehet tudni azt, hogy mennyi a valós mintapont darabszáma. Az valóban 4k vagy 8k. Ahogy beállítod neki, és alul írja hogy épp mennyi a valós mintavételezési sebessége. Illetve én szerintem a szkóp sávszélességét nem csak a 3dB-ből, hanem a felfutási időből is kell számolni. Jobban szeretem azt, ha a sávszélesség=mintavételezés/10-et használják. Ennél is van olyan korlátozás, hogy a Single és normal trigger nem működik a gyors időalapokban, vagy az hogy a kisfrekvenciás hullámot a gyors időalapban nem tudja triggerelni? A Zoyi ZT-703 és Fnrisi akármelyik hulladékának vannak ilyen dolgai. Az árammérő funkciója csak DC-t tud mérni? mi a leggyorsabb freki aminél még jól működik?

A White Noise Signal Generator can be used for a variety of applications across different fields. Here are some of the primary uses: 1. Audio Testing and Calibration • Testing Speakers and Audio Equipment: White noise contains all frequencies at equal intensity, making it ideal for testing the frequency response of speakers, headphones, and microphones. • Room Acoustics: White noise is used to evaluate and optimize the acoustics of a room, identifying resonances or dead spots. 2. Signal Processing and Analysis • Filter Design and Testing: Engineers use white noise to test and validate the performance of filters and signal processing systems. • System Identification: White noise can be used to analyze the behavior of a system by observing its response to a random input. 3. Telecommunications • Noise Figure Measurements: White noise helps determine the noise figure of amplifiers and other telecommunications equipment. • Channel Testing: Used to simulate noise in communication channels and evaluate the robustness of data transmission methods. 4. Health and Wellness • Sleep Aid: White noise is popular for masking background sounds and promoting better sleep. • Concentration and Relaxation: Many people use white noise to create a neutral auditory environment, aiding focus or relaxation. 5. Education and Training • Teaching Tool: Used in signal processing and acoustics education to demonstrate concepts like spectral analysis and filtering. 6. Scientific Research • Random Stimulation: White noise can be applied to systems in fields like neuroscience or physics to study responses to random inputs. • Behavioral Studies: Used in experiments to mask external sounds or study the effects of noise. 7. Electronics and Circuit Design • Testing Circuit Performance: Helps in testing the linearity, stability, and behavior of electronic circuits. • Noise Simulation: Used to simulate the impact of noise on circuits or systems during design and testing. 8. Environmental Sound Masking • Office Sound Masking: In open office environments, white noise can be used to reduce distractions and improve privacy. • Soundproofing Testing: Helps identify leaks or weak points in soundproofing setups. 9. Psychological and Cognitive Studies • Stimulus in Experiments: White noise can be used as a controlled stimulus to investigate brain activity or cognitive processes. 10. Broadcast and Media Production • Noise Floor Analysis: Helps determine the noise floor in recording and broadcast systems. • Sound Effects: White noise can be processed to create specific sound effects for films, music, or games. 11. Instrumentation and Calibration • Calibrating Sensors: White noise can serve as a test input to verify the accuracy of sensors and measurement equipment. • Dynamic Range Testing: Used to evaluate the dynamic range of various instruments. White noise generators are valuable tools for both technical and everyday applications due to their ability to provide a broad spectrum of frequencies in a controlled manner.

What I don't understand about converting 220 volts to 12v or 5 volts is that there used to be a transformer in between, with this a drop is made and induction occurs, the other circuit is not damaged by this. However, I couldn't understand what provides this in this circuit?

Thanks for the video. Good job on describing the functions as I could not find any manual on this FM Receiver. Two questions: When you long press the frequency knob it scrolls "SN ON" or "SN OFF" across the screen. What is SN? Also can you wire a AUX(3.5mm) jack to this board? If so, how will it switch between sources?
@bzoli5706 9 ай бұрын
When switched to SN ON, the radio does not produce any hissing noise when there is no transmission. SN stands for 'squelch', which is used to suppress the background noise when there is no signal. I don't understand the 2nd question. 😞
