Question

EXERCISE 1: Discrete SIPO Shift Register Your first circuit will build a 4-bit Serial-ln-Parallel-Out Shift Register (SIPO) Serial-ln means you will load the 4 bits into the shift register one bit at a time LSB first, using the clock. Para lel-Out on the other hand means that once all bits are loaded, they will be available on the outputs in parallel (ie, all bits together.) 1. Using a 74LS04N Inverter and four 74LS76NC74LS] J-K Flip-Flop gates (use the LS gates not the ICs), construct the 4bit seriakin parallel-out shift register shown below. 2. Use Digital Probes for the LEDs, use Interactive Digital Constants for the DATA, NOT CLEAR, and CLOCK inputs. NOTE that outputs order: Qa, Qb, Qc, Qd is the opposite of the counters we built in previous labs Qb Qc Qa Qd Vcc PR PR PR DAT A C g D NOT CLEAR 3. SAVE your Multisim project as "Discreet Shift Register 4. Verify proper operation of this shift register as follows: 5. Set NOT CLEAR high, set DATA High, Set CLOCK low, then start the simulation. 6. Cycle CLOCK high, then low repeatedly until some of the LEDs are lit. 7. While noting the effect on the LEDs, cycle the CL inputs low by activating then inactivating the NOT CLEAR input. What effect does this have on the LEDs? 8. Set the CL control LOW then return it to HIGH. Set the serial data input (DATA) high and CLOCK the shift register (From low to high to low) once. Continue this until the shift register is filled with 1's. How many clock pulses are required? 9. Feed the clock and serial-in waveforms given below into your shift register, starting at the left and working right. This should load the register with the binary equivalent of 13 (11012). Notice that the number has to be shifted in BACKWARDS, (ie, "1011") to set Qa,Qb,Qc,Qd values to 11012
