It is highly recommended that you practice them. All questions have been asked in GATE in previous years or in GATE Mock Tests. Practicing the following questions will help you test your knowledge. Other applications especially for Priority Encoders may include detecting interrupts in microprocessor applications.Encoders are used to translate the decimal values to the binary in order to perform the binary functions such as addition, subtraction, multiplication, etc.Encoders are very common electronic circuits used in all digital systems.

Then, the output of encoder will be the ( code corresponding to the active High inputs, which has higher priority. So, to overcome these difficulties, we should assign priorities to each input of encoder. If more than one input is active High, then the encoder produces an output, which may not be the correct code.

There is an ambiguity, when all outputs of encoder are equal to zero.

The above two Boolean functions can be implemented as : The truth table for priority encoder is as follows : In this case, even if more than one input is вЂ1вЂ™ at the same time, the output will be the (binary) code corresponding to the input, which is having higher priority. Here, the input, Y3 has the highest priority, whereas the input, Y0 has the lowest priority.

Thus, the RBO terminal is normally low and goes high only if a BCD вЂ0000вЂ™ input is present at the same time as the RBI terminal is high. The above two Boolean functions can be implemented using OR gates :ДЄ 4 to 2 priority encoder has 4 inputs : Y3, Y2, Y1 & Y0 and 2 outputs : A1 & A0. If the RBI terminal is biased high (at logic-1), the seven-segment outputs become disabled in the presence of a BCD вЂ0000вЂ™ input ( decimal zero), and the RBO output goes high under the same condition. Logical expression for A3, A2, A1 and A0 : A3 = Y9 + Y8 The truth table for decimal to BCD encoder is as follows: ThisвЂ™ll open the audio preferences window.

The figure below shows the logic symbol of decimal to BCD encoder : Open the Logic Pro X dropdown at the top left of your screen, open the Preferences menu, and select Audio. This encoder accepts the decoded decimal data as an input and encodes it to the BCD output which is available on the output lines. Each input line corresponds to the each decimal digit and 4 outputs correspond to the BCD code. Figure 2: Binary to BCD Code Converter logic diagram. The decimal to binary encoder usually consists of 10 input lines and 4 output lines. Based on the above given minimized expression for each output, a logic circuit can be drawn as shown in Figure 2. The above two Boolean functions A2, A1 and A0 can be implemented using four input OR gates : The truth table for 8 to 3 encoder is as follows : The figure below shows the logic symbol of octal to binary encoder: Each input line corresponds to each octal digit and three outputs generate corresponding binary code. The 8 to 3 Encoder or octal to Binary encoder consists of 8 inputs : Y7 to Y0 and 3 outputs : A2, A1 & A0. The above two Boolean functions A1 and A0 can be implemented using two input OR gates : Logical expression for A1 and A0 : A1 = Y3 + Y2 The Truth table of 4 to 2 encoder is as follows : The figure below shows the logic symbol of 4 to 2 encoder : At any time, only one of these 4 inputs can be вЂ1вЂ™ in order to get the respective binary code at the output. The 4 to 2 Encoder consists of four inputs Y3, Y2, Y1 & Y0 and two outputs A1 & A0. Therefore, the encoder encodes 2^n input lines with вЂnвЂ™ bits. It will produce a binary code equivalent to the input, which is active High.

So, our logic is C' + S3'.S2' + S3'.An Encoder is a combinational circuit that performs the reverse operation of Decoder.It has maximum of 2^n input lines and вЂnвЂ™ output lines, hence it encodes the information from 2^n inputs into an n-bit code. We are adding вЂњ0110вЂќ (=6) only to the second half of the table. Now, lets move to the table and find out the logic when we are going to add вЂњ0110вЂќ. Note вЂ“ If the sum of two number is less than or equal to 9, then the value of BCD sum and binary sum will be same otherwise they will differ by 6(0110 in binary). Where 1 is 0001 in binary and 4 is 0100 in binary. The value of binary sum will be 1110(=14). Where 1 is 0001 in binary and 5 is 0101 in binary.Д®xplanation: We are adding A(=5) and B(=9). The value of binary sum will be 1111(=15).
