An optocoupler provides galvanic isolation between the sending and the receiving side of an information stream. The signal crosses the galvanic isolation by being transmitted by a light emitting diode (or a similar mechanism), and is received by a light-sensitive device such as a photo diode or resistor.

Common uses of opto couplers include the trigger system of triacs and thyristors, electronic devices dealing with high voltage and current. In those systems, the opto coupler protects the sensitive control logic and equipment that manages the trigger signals from the high power load path.

Other common uses of opto couplers are in computing, where devices need connecting to enable exchange of data and where galvanic isolation is desired to keep both sides decoupled.

Fibre optic data cables are also very similar to an opto coupler. A typical opto coupler has a thin galvanic isolation barrier (a think layer of glass or similar plastic material) between the light transmitting and light receiving sides. A fibre optics "cable" works much in the same way, except the isolating (but light-conducting) barrier is a very long fibre of glass (or a similar material).

What is the relationship between a logarithmic function and its corresponding graph in terms of the log n graph?

The relationship between a logarithmic function and its graph is that the graph of a logarithmic function is the inverse of an exponential function. This means that the logarithmic function "undoes" the exponential function, and the graph of the logarithmic function reflects this inverse relationship.


How to find the roots of a function in MATLAB?

To find the roots of a function in MATLAB, you can use the "roots" function for polynomials or the "fzero" function for general functions. The "roots" function calculates the roots of a polynomial, while the "fzero" function finds the root of a general function by iteratively narrowing down the root within a specified interval.


How can I use the scipy differentiation function to calculate the derivative of a mathematical function?

To calculate the derivative of a mathematical function using the scipy differentiation function, you can use the scipy.misc.derivative function. This function takes the mathematical function, the point at which you want to calculate the derivative, and the order of the derivative as input parameters. It then returns the numerical value of the derivative at that point.

Difference between optocoupler and normal diode?

Purpose: An optocoupler (or optical isolator) uses optics to isolate one circuit from another. The diode in the optical isolator is similar to an LED. The light from this LED controls the gate or base of a transistor. A diode has two terminals, an optocouple will have at least 4. A diode is used to control current flow direction; an optocoupler main purpose is to isolate one circuit from another. etc. etc.
