A diode converts AC to pulsed?
If you put a diode in series with an AC sine wave that goes plus and minus, it will cut off either the positive or negative portion of the waveform, depending on the direction of the diode in circuit. So in effect you have a pulse equal to one half cycle of the sine wave.
What is the difference between a one diode rectifier and a two diode rectifier?
A one diode rectifier is called a half wave rectifier and only allows current flow for the positive portion of the sine wave. A two diode rectifier, or full wave rectifier allows positive current flow during the positive portion of the wave as well as positive current flow during the negative portion of the sine wave. This results in a much cleaner DC power signal. The addition of a capacitor in the output circuit will clean up the signal very nicely.
What is rectifer?
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.
What is the Integration of sine wave?
cos wave
Determine second third and 12TH harmonic of a sine wave?
A sine wave has no harmonics. It only has a fundamental, so the value of the 2nd, 3rd, and 12th harmonics of a sine wave is zero.

Is the output of half wave rectifier exactly a sinne wave explain?
If a sine wave is applied to a rectifier, and the sine wave is strictly AC (no DC offset), the output will be 1/2 the wave - it will be clipped near zero, as the diode prevents reverse voltages. So the output will NOT be a perfect sine wave.
When the diode in an envelope detector rectifies the electrical current how come the output isn't buzzy like when a sine wave has the bottom completely cut out the output sounds buzzy?
because the capacitor connected to the diode on the output side "filters out" the areas that would normally be chopped out by the diode. It does that, for example, by maintaining the voltage during the cut out portion of the sine wave.
What effect does an open diode have on the output voltage of a half wave rectifier and on a full wave rectifier?
An open diode will result in no output from a half wave rectifier, and an open diode will cut the output of a full wave rectifier in half.
What is the difference between a one diode rectifier and a two diode rectifier?

How do you generate cos wave from sine wave?
By shifting the sine wave by 45 degrees.
Why isn't the current coming out of a transformer not a sine function?
The voltage of a transformer should be a sine wave but if the transformer is overloaded with excess voltage there could be nonlinear effects in the magnetic core that cause harmonics (i.e. departure from a sine wave) in the voltage. The current is determined by the load. If the load is resistive the current and voltage have the same waveform (by Ohm's law) but if the load is nonlinear, a diode rectifier for example, the current will depart from being a sine wave.

What is the Fourier transform of a sine wave?
The Fourier transform of a sine wave is a pair of delta functions located at the positive and negative frequencies of the sine wave.
Definition of sine wave?
A sine wave is the graph of y = sin(x). It demonstrates to cyclic nature of the sine function.
How could you print out a sine wave of your voice on a laser printer?
The voice is not a sine wave.
How do you change AC into DC and DC into AC?
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.
