flipflop What happens when theres no specific input variable on a logic diagram using a JK flip flop
Q1 and Q2. to form a table, on the left side, list the the four possible states of Q1, Q2; on the right side, write the values that Q1 and Q2 will assume after the next clock pulse. The table will then contain a complete description of the state machine..... -
Achieve communication between MCU and accelerometer trough I2C nor SPI. I observed that shorting PLL filter input in device causes no effect on both gyro readings and operation. My assumption is that PLL is present only in accelerometer part of the device. I.... -
Make a 555 timer base circuit such that O/P pin of 555 is held LOW by default at power on, and the I/P pin is held initially at HIGH at power on. The main requirement of my circuit is that until I/P pin is held LOW for say 200ms, then only the O/P pin must.... -
The basic problem for me is that gates on a logic circuit appear to be creating power from nothing, which is impossible. For example imagine two NOT gates connected in sequence: To my uninitiated mind what seems to be happening is that the first NOT gate.... -
The AND output will be high with both switches closed. However, nothing is guaranteeing the level of the inputs when the switches are open, so the result could be anything. Olin Lathrop Mar 6 `13 at 19:58.. -
There are chips that have AND/OR/NOT gates, but I was wondering if there`s a single one that have all of the ones I need - if not, then what should I use specifically Any reason it has to be those particular gates For example a package with with four NOR.... -
Invert a signal to drive fets with hard/fast rise and fall times. I was told in another thread to use an inverter (NOT chip). This makes perfect sense to me since logic chips are always hard ON or OFF by design. But I`ve never worked with logic chips before..... -
For a 4-bit Carry Look Ahead Adder have 3 gate delays for all carry bits and 4 gate delays for all sum bits, while it is stated as 7 and 8 in case of ripple adders. How, was this calculated The image of 4 bit carry look ahead adder is shown below:.. -
I opened remote of a RC car and extended wires out of backward, forward, left and right switches. So when I ground anyone of then the circuit completes andit sends signal to the car. I wanted to close the circuit using one of the I/O pins of BeagleBone.... -
You check the voltage at the anode and cathode of the diodes and determine whether or not it is conducting. With a current source I am kind of confused on what to do. I can`t determine the state of the diodes for a given input combination (00, 01,10, 11).... -
What that flip-flop does, but mostly why those two NAND gates aren`t just inverters. and why the one on the bottom (and the inverter next to it) are even there. You should wait with accepting the answer and allow others to have a look and write up their.... -
This is a circuit diagram for logic probe that is based on single CMOS IC. This logic probe shows three logic condition, High, Low, and Pulsing. Ind addition, there is no LED`s will glow if the probe input is neither hi or lo (the high impedance state of.... -

This mini Logic analyzer is a tool for you to watch on LCD the logic transitions 0 or 1 of a digital data signal. A digital data signal can be found on the output pin of TSOP-1730 Infrared Receiver, on the Transmit and receive pins of MAX-232 chip (RS-232),.... -
The count advances as the clock input becomes high (on the rising-edge). Each output Q0-Q9 goes high in turn as counting advances. For some functions (such as flash sequences) outputs may be combined using diodes. The reset input should be low (0V) for.... -
When testing circuits with a logic probe, it is sometimes difficult to watch the LEDS on the probe to determine the logic state. With this probe the logic states are audible. This probe is designed for TTL circuits only but could be modified for CMOS. The.... -

Design a circuit with four single-bit inputs X, Y, T, and Z, but only one single-bit output E. A two bit control code word S0S1 selects which of the four inputs is propagated to the output (the selection code is not unique). Your answer should be in the form.... -
The circuit presented here usesNAND logic gates of Hitachi HD seriesIC HD74LS00, which is a quad NANDIC. Special technique has been employedto obtain three-state operation usingjust a single IC. Gate N1 is wired such that when theoutput of gate N1 is at.... -

The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
