Frequency counters are digital indicating meters for accurate measurement and display of square wave and pulse input signals

Digital thermometers are portable temperature sensing devices that have permanent probes and a digital display

Phase-locked loop (PLL) frequency synthesizers are electronic devices that produce frequencies coherent to a reference frequency

Electronic counters and electronic timers are completely electronic units for performing a variety of counter or timer functions

Frequency-to-voltage converters accept a signal and convert its frequency to a corresponding analog voltage level

Counter and timer boards are computer cards that perform digital counting and/or timing functions

Digital counters are integrated circuits used for counting events in computers and other digital systems

Electromechanical counters and electromechanical timers accept inputs to operate mechanical display, such as rotating wheels or knobs

Digital-to-analog converter (DAC) chips convert digital signals that represent binary numbers into proportional analog voltages

Digital dividers are integrated circuits that divide the frequency of an input signal by a divisor value

Digital-to-analog converters (DAC) transform a digital number into a corresponding analog voltage or current

Digital signal processors (DSPs) are specialized microprocessors designed specifically for digital signal processing, usually in real-time. DSPs can also be used to perform general-purpose computations, but are not optimized for this function

Radiation detectors are used for medical diagnoses, radioactive dating measurements, and measurements of background radiation, activity levels and radiation doses.

Digital bargraphs measure process and electrical variables such as pressure, flow, temperature, speed, current, and voltage. There are two main types of products: light emitting diode (LED) and liquid crystal display (LCD).  

Flip-flops are digital logic devices that synchronize changes in output state (1 or 0) according to a clocked input
