DESIGN AND CONSTRUCTION OF A FREQUENCY COUNTER
ABSTRACT

Digital frequency counter is an electronic instrument, or component of one, that is used for measuring frequency. Frequency counters usually measure the number of oscillations or pulses per second in a repetitive electronic signal.
It detects the frequency value and displays that value with the help of the LCD employed. Depending on the power supply the value of the frequency on the LCD changes. Most frequency counters work by using a [counter] which accumulates the number of events occurring within a specific period of time. After a preset period (1 second, for example), the value in the counter is transferred to a display and the counter is reset to zero. If the event being measured repeats itself with sufficient stability and the frequency is considerably lower than that of the clock oscillator being used, the resolution of the measurement can be greatly improved by measuring the time required for an entire number of cycles, rather than counting the number of entire cycles observed for a pre-set duration. Frequency counters are commonly used in laboratories, factories, and field environments to provide direct frequency measurements of various devices.
