Pipo Shift Register Truth Table. This circuit consists of three d flip flops which are cascaded. Parallel in parallel out shift register pipo.
No extra decoding circuit is needed to determine what state the counter is in. The truth table of the piso shift register emphasizing the loading and retrieval processes is shown by table i while the corresponding wave forms are shown by figure 2. Parallel in parallel out shift register pipo.
This working is further emphasized in the table i and figure 3.
Parallel in parallel out pipo shift register. Similar to the serial in to serial out shift register this type of register also acts as a temporary storage device or as a time delay device with the amount of time delay being varied by the frequency of the clock pulses. The pipo shift register is the simplest of the four configurations as it has only three connections the parallel input pi which determines what enters the flip flop the parallel output po and the sequencing clock signal clk. Parallel in parallel out shift register pipo.
