Methods of amplitude modulation can be put in the two categories namely Linear modulation methods and Square law modulation methods. Linear modulation method utilizes the linear region of the current voltage characteristics of the amplifying device that is transistor or electron tube. Square law modulation method utilizes the square law region of some current voltage characteristics of a diode or transistor or electron tube. A large number of linear modulation methods have been devised and have been used to varying degree. These methods are namely linear shunt plate modulation or anode choke modulation, linear series plate modulation, grid bias modulation, cathode modulation, suppressor grid modulation, screen grid modulation, collector modulation.
Square law modulation circuits make use of non linear current voltage characteristics of diodes or triodes and are in general suited for use at low voltages. Important square law modulation methods are square law diode modulation and balanced modulator.

How is balanced modulator different from diode bridge modulator?
A diode bridge modulator is one kind of balanced modulator.
What is square law device?
A square law device is something where either current or voltage depends on the square of the other. For example, a saturated MOSFET has I proportional to V^2. A diode's characteristics also has a square but it's not as clean. It's exponential, and through a Taylor series you get linear, square, cubic terms.... Anyway, it's useful because you can use it as a modulator or mixer. Adding voltages is easy (just use resistors or an op amp) but multiplying is hard. With a square law device like a MOSFET you can do this: Now if you follow that with a bandpass filter centered on you just get Amplitude modulation.
Does the diode satisfy ohms law Explain?
no
What is a non example of ohm's law?

Difference between product modulator and balance modulator?
what is the difference between balance n product modulator
What is a diode modulator?
A diode modulator is a type of AM modulator constructed using diodes. One type of diode modulator is the ring modulator shown in the image.
How is balanced modulator different from diode bridge modulator?
A diode bridge modulator is one kind of balanced modulator.
Why balanced modulator is called balanced modulator?
the output from a balanced modulator consists of modulating freq also. this can be eliminated in a diode modulator by adding two more diodes, making a diode ring. therefore called ring modulator

Does a 1988 Chevy 1500 have a transmission vacuum modulator?
More Info, If You Do Not Find A Modulator, You Could Have a Different Trans. If You Have A Square Pan With 16 Bolts Then You Have A 4L60 or TH700( no modulator on these) If the pan is oval and 17 Bolts Has 4L80 ( no modulator on these) Hope This Helps You Should Have A TH400 Trans & It Does Have A Modulator.
