The difference between linear and non-linear PCM is LPCM represents sample amplitudes on a linear scale. LPCM specifies that the values stored are proportional to the amplitudes, rather than representing say the logarithm of the amplitude or being related in some other manner. While non-linear each step size may vary in amplitude.

What is square law diode modulator?
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.
Is rectifier a non linear device?
diode is nonlinear device,so device from diode is also nonlinear
What are the Examples for linear ic and nonlinear ic?
op amp linear ic 7805 non linear ic
Why angle modulation is called exponential modulation?
The reason it is called exponential (non-linear) modulation is that the information is encoded within the phase of carrier.
Why is a cascode current mirror better than a simple MOSFET current mirror?
In simple MOSFET current mirror, the load current does not follow a linear relationship with reference current (ie for short channel MOSFET's multiplying factor due to channel length modulation cannot be neglected). But by cascoding the output resistance can be increased and since output resistance follows an inverse relationship with lambda (channel-length modulation parameter), the multiplying factor due to channel length modulation reduces to one and a linear relationship is obtained between reference and load current.
Why is Angle Modulation called nonlinear modulation?
angle modulation is called non linear modulation because the information is stored in phase of the carrier signal
What is nonlinear devices?
Nonlinear devices are components that do not follow a linear relationship between input and output. This means that their response is not proportional to the input signal. Examples include diodes, transistors, and nonlinear capacitors. Nonlinear devices are often used in electronic circuits to perform functions like signal processing and modulation.
What is the difference between linear and nonlinear demand functions?
distinguish between linear and non linear demands funcions
What is the difference between linear and non linear problems?
Nonlinear do not satisfy the superposition principle. Linear problems, as implied, do.
What is similar between linear and nonlinear motions?
They are both types of motion.
What is the difference with a linear and nonlinear scale?
The differences between the these two is that linear scale shows the relation between the map distance and the ground distance. The nonlinear scale do not show the relation between the map distance and the ground distance.

Is the function y8x linear or nonlinear?
linear
What is a non linear realtionship?
A nonlinear relationship is one that cannot be expressed using a line. y=3x is a linear relationship between x and y. y = log(x) is nonlinear.
What is the difference between nonlinear and linear system?
Linear system follows principal of superposition and homogeneity and Non linear system does not follow the same.
