2. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   Sine wave inverters with more than three steps in the wave output are more complex and have significantly higher cost than a modified sine wave, with only three steps, or square wave (one step) types of the same power handling. Switched-mode power supply (SMPS) devices, such as personal computers or DVD players, function on modified sine wave ...

   en.wikipedia.org/wiki/File:Modified_sine_wave...

   English: Waveform of an automotive inverter producing 120 V AC, approximately 60 HZ|, from the vehicle's 12 volt cigarette lighter power outlet. This three-step waveform uses alternating positive and negative pulses to approximate the peak to peak and RMS values of a sine wave.

4. In-phase and quadrature components - Wikipedia

   By just amplitude-modulating these two 90°-out-of-phase sine waves and adding them, it is possible to produce the effect of arbitrarily modulating some carrier: amplitude and phase. A phasor for I/Q, and the resultant wave which is continually phase shifting, according to the phasor's frequency. Note that since this resultant wave is ...

5. Frequency mixer - Wikipedia

   en.wikipedia.org/wiki/Frequency_mixer

   Frequency mixer symbol. In electronics, a mixer, or frequency mixer, is an electrical circuit that creates new frequencies from two signals applied to it.In its most common application, two signals are applied to a mixer, and it produces new signals at the sum and difference of the original frequencies.

6. Recreational vehicle terms - Wikipedia

   The more expensive versions are 'sine-wave' or 'full sine-wave' inverters. The modified- or quasi-sine wave inverters work well for most RV uses, but most inverter manufacturers recommend the use of full sine wave inverters to power televisions, VCR players and recorders, DVD players, computers, printers, fax machines and other electronic devices.

7. Talk:Power inverter - Wikipedia

   en.wikipedia.org/wiki/Talk:Power_inverter

   A modifed sine wave inverter may cause certain types of loads, such as motors, to operate less efficiently than when powered by [alternating current in the form of] a pure sine wave, whether that sine wave be from a "pure sine wave" inverter or regular AC power from the wall outlet.
