An Encoder functional device performs an operation which is the opposite of the

Decoder function. The Encoder accepts an active level at one of its inputs and at its output

Generates a BCD or Binary output representing the selected input. There are various types of

Encoders that are used in Combinational Logic Circuits.

Binary Encoder

The simplest of the Encoders are the 2n-to-n Encoders.

Priority Encoders

Priority Encoders remove the problem highlighted earlier with simple Binary Encoders.

Priority Encoders have necessary logic to activate the outputs corresponding to the highest

Priority input when multiple inputs are asserted simultaneously.

Boolean expressions for the three outputs O2, O1 and O0 of an 8-to-3 Priority Encoder

Are can be written in terms of variables.

Cascading Priority Encoders

The 74XX148 Priority Encoder has active-low inputs and active-low outputs. The

Encoder also has an active-low enable input E1 which enables or disables the outputs. The

Group Select GS active-low output is asserted when any one of the inputs is asserted. The

Enable output EO signal is used to cascade multiple Encoders to form larger Encoders. The

EO output is connected to the EI input of the Encoder which handles lower priority inputs. 

tell me which encoding will use by institute by given scenario in gdb topic.

7-segment Display

An LED or Light Emitting Diode, is a solid state optical PN-junction diode which emits light energy in the form of “photons” when it is forward biased by a voltage allowing current to flow across its junction, and in Electronics we call this process electroluminescence.

In most practical applications, 7-segment displays are driven by a suitable decoder/driver IC such as the CMos  from a 4-bit BCD input. Today, LED based 7-segment displays have been largely replaced by liquid crystal displays (LCDs) which consume less current.

not a answer just to discus

from where you get this?

just searching sites on google,trying  to find something relevant from where atleast i can understand what to do!

which encoding mechanism will be used by the institute for automating this task?


You have to give valid arguments by keeping in view the following points:


Display time

first we have to know what is process behind converting photosensor to 7_segment?

i think then we will be able to guess this process mach to which encoding technique/

Priority Encoders can not be used becaos it requir more time for process

ok priority encoder use nai hona .mean ho ga inhe encoders main sey binary ya cascading encoders?

kisi site se b help nai mil rai question kuch ajeeb sa hai.

agr kisi k pass is se related koi information hai to share krain becaz last 8 hours left.

yes question is cconfusing.

.i dont get what they exactly want to ask in GDB .as
In your opinion which encoding mechanism will be used by the institute for automating this task?
and asn is also in question statement that is"They automated this task by using photo sensors to take readings"
someone say asking this thing
 "between two tecnic which is good by keeping in mind accuracy and time"
but ans of this is also given as
 "Manual is not precise"
