________________________________________ Introduction - Clocked SR Flip-Flop: The clocked SR flip-flop shown in Figure 4 consists of a basic NOR flip-flop and two AND gates. The outputs of the two AND gates remain at 0 as long as the clock pulse (or CP) is 0‚ regardless of the S and R input values. When the clock pulse goes to 1‚ information from the S and R inputs passes through to the basic flip-flop. With both S=1 and R=1‚ the occurrence of

type of system uses storage elements called flip-flops that are employed to change their binary value only at discrete instants of time. Sequential circuits have a clock signal as one of their inputs. All state transitions in such circuits occur only when the clock value is either 0 or 1 or happen at the rising or falling edges of the clock depending on the type of memory elements used in the circuit. * Asynchronous sequential circuits - This is a system whose outputs depend upon the order in which

receives radio waves from the satellites in orbit‚ which keeps track of how far away each satellite is. In general there are normally 8 or so satellites "visible" to a GPS hand-held receiver at any given moment. Each satellite contains an atomic clock. The satellites send radio wave signals to the GPS receivers so that the receivers can find out how far away each satellite is at a given time. From this‚ the receiver is able to work out how far it is from the satellite. Since we know how fast radio

As the DS1307 Real Time Clock chip with battery back-up is used‚ there will be no disturbances for the programmed on/off timings even in power failures. Three switches are provided for entering the required timings. These switches made this project user friendly. 16X2 LCD display is provided to display the alarm times and current time. DS1307 is interfaced to the microcontroller for real timing performance. A 3V battery

performance very high. Indeed‚ the speed improvement (higher clock rates) due to the technological evolution is unable to fit the demand. Consequently‚ new architectures must be devised. Targetting the applications to an FPGA device is an issue for this paper‚ as it allows low-cost designs. The simple and evident serial implementation is a classical hardware implementation of the CRC algorithm. Unfortunatly‚ on an FPGA implementation with maximal clock frequency of 250 MHz‚ maximal data rate is limited to

Our group decided to make an Automated Timekeeping System with payroll summary replacing their Punch card Clock. The system will be made via Visual Basic. The program will include a timekeeping system and payroll template that will be utilized whenever an employee would like to request for a vacation leave or would like to file a sick leave.

Intel introduced their first processor‚ a 4004‚ in November of 1971. This first processor had a clock speed of 108 kilohertz and 2‚300 transistors. It was used mainly for simple arithmetic manipulation such as in a calculator. Ever since this first processor was introduced the market has done nothing but soared to unbelievable highs.

calculate the period using small angular displacements and compare the results. We will also explore the effects on the period when the angular displacement is not “very small” (in essence > 10°). Lastly we will look at creating our own pendulum clock to create a period of 1 second. In part B (Mass on a Spring) we will experiment with oscillations of a spring. We will then estimate the spring constant. Based on the spring constant we will then calculate the mass need to create a period of 1
