Frequency Counter and Timer
In counter mode, it provides 1 Hz resolution up to 100 MHz. In timer mode, the maximum resolution is 0.0000001 Hz up to 1 Hz. The resolution decreases by one digit for each additional decade. Multiple frequency updates per second...
Frequency counter BNC input schematic
This is a CMOS-compatible (and ideally also TTL-compatible) input that includes over-voltage and under-voltage protection. Schmitt triggers are utilized to accommodate inputs with long transition times. It has been verified to function at frequencies up to 30 MHz.
The described circuit...
10Mhz Frequency Counter Circuit
The circuit comprises an ICM7208 seven-decade counter (U1), an ICM7207A oscillator controller (U2), and a CA3130 biFET operational amplifier (U3). Integrated circuit U1 counts input signals, decodes them into a 7-segment format, and outputs signals to drive a 7-digit display....
Frequency counter 400Hz to 50MHz with PIC 16F84
It consists only from Microchip PIC 16F84 cpu and LCD text module. Author states that this counter is capable metering frequencies from 400Hz to 50MHz. I used faster, 20MHz version of 16F84A-20I/P, and it managed to count 80MHz oscillator output....
Frequency counter up to 1MHZ
The MK50398 is one modern decimal counter up/down of six tens, with control of screen LED of seven segments and flip-flop of storage. Counter it can measure additive and abstractively. The IC MK50398 is ideal for manufacture frequency counter as...
Frequency Counter Tachometer
For convenient reading, the display of this tachometer circuit shows the reading in hertz directly. The conversion time will be equal to the gating time.
The tachometer circuit is designed to provide a direct digital readout of rotational speed in hertz,...
gear display
A universal digital gear display that can be installed on any motorbike. This is a low-cost solution based on simple TTL digital technology without software programming.
The universal digital gear display is designed for easy installation on a variety of motorbike...
Watch Timer circuit
A schematic for a watch timer was found in a hobby electronics book. The circuit adapts a frequency counter to measure intervals. Watch ticks are clipped, shaped, and formed into a square wave. This square wave is utilized to gate...
Frequency counter Counter schematic
The counter utilizes five cascaded CD40110 chips, which integrate a decade counter, a display latch, and a 7-segment LED driver within a single package. The decimal points are driven by an IC8x. This counter supports both up and down counting,...
