Sine Waveform Output by Using DAC - EEWeb
2014年10月17日 · It is a table that switches values every 200 µs from 0.0 V to 5.0 V of the analog output voltage and outputs the sine waveform of 1 cycle: 50 Hz every 100 times when VDD is 5.0 V. Use the value calculated based on the following calculating formula for the D/A conversion value: Analog output voltage of the D/A converter (DACS0)
The Basic Quantities of AC Waveform - EEWeb
2012年3月20日 · An AC waveform is constantly changing its polarity every half cycle alternating between a positive maximum value and a negative maximum value with regards to time. This signifies that the AC waveform is a time-dependent signal with the most common type being that of the periodic waveform which is the resulting product of a rotating electrical ...
Sine Wave Generator with 1KHz Frequency - EEWeb
2012年1月15日 · In order to acquire a good overload capability, the circuit should feature a variable output, a low output impedance, and a low distortion. An amplitude waveform that is a long term output and stable is being ensured by a small …
it that relates more in shape to a sine wave. This can be seen in Figure 2, which displays how a modified sine wave tries to emulate the sine wave itself. The waveform is easy to produce because it is just the product of switching between 3 values at set frequencies, thereby leaving out the more complicated circuitry needed for a pure sine wave.

Learn About the AC Phase Difference - EEWeb
2012年2月28日 · A cosine wave is a signal waveform with a shape identical to that of a sine wave, except each point on the cosine wave occurs exactly ¼ cycles earlier than the corresponding point on the sine wave. The sine and cosine functions are very similar to each other since one curve can be shifted along a bit with a distance of 90 degrees to get the ...
Op-Amp-Based Wien Bridge Oscillator - EEWeb
2012年1月14日 · The sine wave generator is an exceptional instrument for producing waves with wave drivers and speakers. It permits variation in the amplitude of the sine wave and works on frequency range of 1 to 800 Hz. A fundamental frequency for a particular configuration can also be learned by the generator.
R/2R sine wave with PIC/Arduino - EE Web
2019年7月3日 · A sine wave is calculated from the values for the sine of an angle from 0 to 360 degrees. So you can do this (I’m a lazy sod, so I got Excel to do it for me). Now you have a 5-bit DAC, so you have 32 possible states (in binary from 00000 to 11111).
Phasor Diagram: Overview, Applications, and Examples - EEWeb
2012年2月23日 · The main value of phasor diagrams is that they can be used, not only to represent waveform diagrams, but also in carrying out calculations involving ac waves. The calculations involve any of the common values such as peak values, phase angles, RMS, etc. it is much easier and quicker than performing the calculations on waveform diagrams.
