For an 8-to-3 binary encoder with inputs I0-I7 the logic expressions of the outputs Y0-Y2 are: Y0 = I1 + I3 + I5 + I7 Y1= I2 + I3 + I6 + I7 Y2 = I4 + I5 + I6 +I7. 1 4 1 5 5 4 3 2 1 1 3 1 2 1 1 1 0 GS EO EI 7 6 5 4 3 2 1 0 1 6 9 7 6 A0 A2 A1 8 VCC +5 V 7 4 L S 1 4 8 3 3 0 Q 3 3 0 Q 3 3 0 Q Gambar 1. Discussion 1. Some encoders also provide a 1V p-to-p sin/cos output for real-time control, since the on-demand absolute encoder data can come in too slowly for many control loops. Truth Table – N = 12 G = 2. Table 9. Igual tenemos los valores correctos, pero internamente el Example 3: Quad 2X1 Mux Given two 4-bit numbers A and B, design a multiplexer that selects one of these 2 numbers based on some select signal S. The 3-to-8 decoder symbol and the truth table are shown below. com sales@encoder. JUMPER CABLE WITH POWER SUPPLY. VHDL program Simulation waveforms As shown in the figure, the input-output waveforms look similar to the decoder because the encoder is just the reverse of the decoder. The 74x148 is a commercially available, MSI 8-input priority encoder it has an enable input, EI_L, that must be asserted for any of its outputs to be asserted.
