The clock pulse generator (CPG) described here was designed as a portable, low-cost device to generate both an accurate time standard and a timing trace that was easy to read, for use in research on temporal phenomena.
What does a pulse generator do?
A pulse generator is either an electronic circuit or a piece of electronic test equipment used to generate rectangular pulses. Pulse generators are used primarily for working with digital circuits, related function generators are used primarily for analog circuits.
How does a clock pulse work?
The clock pulses are at a frequency that is much higher than the sampling pulses, and while a voltage is being held at the input, the clock pulses pass through the gate and are counted. The clock pulses are also the input to the integrator, whose output is a rising voltage.
How are clock pulses generated?
A clock signal is produced by a clock generator. Although more complex arrangements are used, the most common clock signal is in the form of a square wave with a 50% duty cycle, usually with a fixed, constant frequency.
What is the importance of clock pulse?
Clock signal or pulse is used in digital circuits of sequential circuits for differentiating output with time . As in sequential circuits output is fed back to input and new output will be given after every clock pulse.
What is a pulse generator in a pacemaker?
A pacemaker signals the heart to beat when the heartbeat is too slow or irregular. A pulse generator is a small metal case that contains electronic circuitry with a small computer and a battery that regulate the impulses sent to the heart.
How does a pulse generator in an electronic ignition system work?
The pulse generator generates an electrical pulse to signal when the spark is required. The solid state control module makes and breaks electronically the primary current for the ignition coil by amplifying and processing the signals received from the pulse generator.
What is the difference between clock and pulse?
Your microcontroller may have a 16 MHz clock, then the clock generates 16 million pulses per second. So a clock signal consists of an indefinite series of pulses. A pulse is sudden change in signal level, in a digital signal from low to high or vice versa, and after some time a return to the original level.
Why do we use clock in microcontroller?
In order to control the flow of data between the different building blocks of the microcontrller one needs a clock. So, the clock is needed to manage the operation of the microcontroller. The clock is needed also for the streaming the data across the communication ports.
What is clock microprocessor?
Every microprocessor has an internal clock that regulates the speed at which it executes instructions and also synchronizes it with other components. The speed at which the microprocessor executes instructions is called clock speed.
What are the types of clock pulses?
There are two types of sequential circuit, synchronous and asynchronous. Synchronous types use pulsed or level inputs and a clock input to drive the circuit (with restrictions on pulse width and circuit propagation). Asynchronous sequential circuits do not use a clock signal as synchronous circuits do.
What is the difference between clock and enable?
A clock (better represented as clk) is a signal which is used to make the flipflop work at its positive or negative edge (in exceptional case both edge). But, an enable is a signal which makes the flipflop function as long as it is high (1). It can be made low (0) to make the flipflop stops its function.
