2024年12月15日 · Advice about digital (WS2811) signal amplifier: 4K signal generator from digital circuits: DC motor controller, controlled by digital voltage signal: Describe the design of a circuit that can accurately convert an analog voltage signal ranging from 0V to 5V into a digital representation: Digital Analog Signal

2019年3月15日 · A digital waveform is an analog signal with discrete values. Even more precisely, what identifies a signal as being digital is not the signal itself, but the drivers and receivers that create the signal and respond to the signal. In other words, it is the application of the signal that defines if the signal is considered to be digital.

2024年10月26日 · Through analysis, devise your own signal generator, capable of generating following waveforms of desirable amplitude and frequency: 1. Square wave (bonus for varying duty cycle) 2. Sine Wave 3. Sawtooth Wave The signal generator design should include the capability to adjust signal frequency and amplitude.

2010年2月21日 · This sensor then sends a 5v pulsing square wave signal for the ECU to read. This set up means per revolution there are 58 pulses sent to the ECU a 2 pulse gap then another 58 pulses. The engine now in the car has a simple 4 pulse coil pack which uses a standard 4 pulse per revolution 5v signal to drive the tach.

2020年4月10日 · Ripples in square wave output of LM7171 high speed OpAmp. Digital Design: 19: Oct 26, 2021: E: square wave voltage level shifter: Digital Design: 1: Apr 19, 2010: J: Square Wave output to DC Level: Digital Design: 3: Mar 16, 2010: P: convert sin wave (withe dc level) to square wave ? Digital Design: 6: Mar 2, 2007

2013年5月15日 · 3. The 256 bytes data of sine wave saved into the 8 data bits EEPROM. Square wave → 8 bits Binary counter → sine wave EEPROM → 8bits DAC → Op Amp Waveform shaping → sine wave The input frequency divided by 256, so the output frequency are equal to input frequency /256. I'm not sure all the described is correct or not.

2024年8月23日 · The sim ability to view a wave in time domain (oscilloscope) and frequency domain FFT or spectrum is fundamental to understanding wave shaping. Plugging hundreds of wires between modules has been, and may be necessary later however software is doing amazing things digital some analog will remain.

2012年1月1日 · The RMS value is what constant DC voltage will give the same heating effect as the signal of arbitrary wave form. Hence mathematically, you have to compute the integral of the square of the amplitude and then take the square root. So when you square the negative portion, it is the same value as the positive part.

2021年9月24日 · Right, you can tap into the 25% duty cycle 1kHz signal (1000 uSec period). Use that to trigger the cd4538 chip. Set the capacitor and resistor on the chip to create a 100 uSec pulse.

2017年4月4日 · For example to generate a 100kHz sine wave with just 5 points per half cycle, you need a dac that allows you to change points at the rate of 1MHz (10 times the sine wave frequency). If you want to have better resolution like 10 points per half cycle, then you need a dac capable of going at 2MHz (20 points per full cycle, 100kHz sine).
