Filter the square wave with a low-pass filter sharp enough to remove all frequencies
above the frequency of the square wave.
A: by over driving the sine wave through a buffer
Though it is not possible to get a mathematically perfect square wave from a sine wave, it is possible to get a reasonably close square wave from a sine wave. A clipper circuit is one which clips off the top of a sine wave thus giving it a flat top. Clipper circuits find their applications in electronics but not in electrical engineering (that deals with bulk of the power that we use, both at home and in industry). You can also use a comparator, detecting the zero transitions, and producing a digital output which will be close to a square wave. Squareness will be dependent on symmetry, of course.
By switching circuits or transistors that turn on and off the polarity. This usually results in a square wave output. Then capacitors charge and discharge to smooth out the square wave to resemble the AC sine wave. The better or more expensive the inverter, the closer to an actual sine wave it gets.
The three waveforms in the trigger circuit of an oscilloscope are the sine wave, square wave and saw tooth wave.
When a low pass filter is used with a sine wave input, the output is also a sine wave. The output will be reduced in amplitude and phase shifted when the frequency is high, but it is still a sine wave. This is not the case for square or triangular wave inputs. For non-sinusoidal inputs the circuit is called an integrator.
An electronic oscillator is an electronic circuit that produces a repetitive electronic signal, often a sine wave or a square wave.
Schmitt trigger converts any type of waveform (such as sine,triangular.........)to square wave.So it is called Square wave converter.

Square
There is more than one technique. The most common is to use an electronic switch to convert the DC into a square wave, the square wave is filtered to make it a (rough) sine wave. This can then passed through a transformer to the desired voltage. The advantage of this system is that it is very efficient, the disadvantage is that the sine wave produced isn't all that good a sine wave and some devices (AC motors, for example) sometimes have problems when being powered by inverters. An alternative is to use an oscillator to produce the sine wave. This produces a better sine wave, but is less efficient.
how squre wave convert into sine wave incase of inverter
In most circumstances a full wave diode bridge is used to convert AC into DC. Along with inductors and capacitors used as filters, the DC ripple is smoothed out to a very stable DC voltage. This is the method used in DC power supplies. To convert from DC to AC an inverter is used. Today most inverters use the modified sine wave method which brings the sine wave closer to a AC generated sine wave. Older inverters used an on - off switching procedure to generate a square sine wave. Modern electronics do not work well with square wave generation.
we cannot use transformer because transformer cannot change frequency . . .
If a square wave is used instead of a sine wave in a transformer, the output power will operate at a different frequency. This will produces varying levels of voltage and amperage based on the wave.

A: ANALOGUE IT can be AC or DC it is up to the application involved An analog signal can be a sine wave, a square wave a sawtooth wave or any other varying waveform
It is more reasonable to use square wave rather than sine wave signal to determine slew rate. Both signal sources serve as a functional generator with the sine wave providing high purity waves.Ê
Because the laws of basic AC circuit theory only apply to a true sine wave. Other waveforms, such as square or sawtooth, are imperfect recreations of a sine wave with many harmonic frequencies present.
