You can obtain a square wave from using two zener diodes which have a threshold significantly under the sinusoidal signal. For example: An input sinusoidal signal at 50V with two 10V zener diodes, the first in foward bias and the second in reverse bias. The output voltage will have a square wave form with 20V peak to peak.
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
Schmitt trigger converts any type of waveform (such as sine,triangular.........)to square wave.So it is called Square wave converter.
it is used to select the type of input we want to give to any of our ckt's.... Input's such as sine, square, triangular, pulse etc....
The RMS (root mean square) of the peak voltage of a sine wave is about 0.707 times the peak voltage. Recall that the sine wave represents a changing voltage, and it varies from zero to some positive peak, back to zero, and then down to some negative peak to complete the waveform. The root mean square (RMS) is the so-called "DC equivalent voltage" of the sine wave. The voltage of a sine wave varies as described, while the voltage of a DC source can be held at a constant. The "constant voltage" here, the DC equivalent, is the DC voltage that would have to be applied to a purely resistive load (like the heating element in a toaster, iron or a clothes dryer) to get the same effective heating as the AC voltage (the sine wave). Here's the equation: VoltsRMS = VoltsPeak x 0.707 The 0.707 is half the square root of 2. It's actually about 0.70710678 or so.
For a sine wave ONLY - and assuming you are talking plus and minus 100V (200V peak to peak) - the RMS voltage is about 71V. (One half square root of 2 * single sided peak value)
sine[theta]=opposite/hypotenuse=square root of (1-[cos[theta]]^2)
Filter the square wave with a low-pass filter sharp enough to remove all frequencies above the frequency of the square wave.
Square
The square root of two over two.
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.

Another name for a rectifier is a diode. Diodes are used to change AC into DC. They block current when placed in an electrical circuit on one half of an AC sine wave. As a sine wave leaves zero volts and begins climbing to a positive voltage along with the current, the diode allows the electrons to pass. It conducts until the sine wave reaches zero again. At the start of the negative half of the sine wave the diode blocks the passage of electrons right through to the end of this half cycle. This voltage is known as pulsating DC or half wave rectification. One conductive pulse every cycle. Full wave rectification is when 4 diodes are assembled back to back so that 2 of the diodes are conducting on the positive half cycle and the other 2 diodes are conducting on the negative half cycle. This diode set up is known as a full wave bridge. The output voltage is smoother in this configuration but still has a voltage ripple. This ripple is usually smoothed out with capacitors. This is usually the components of DC power supplies.
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.
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.
