I once built a frequency counter using plain TTL chips. The hi-tech frequency counter board Sneaking up behind.

How to build a box for our frequency counter? Frequency counter 1Hz-100Mhz with LCD display and RS232 interface

digital, it can offer fast switching between output frequencies, fine frequency resolution, and operation over a broad spectrum of frequencies.

The exact frequency of the PWM period can be determined with the following equation: f = clk / 2 (2 C_COUNTER_WIDTH ) C_CLOCK_DIVIDER Equation 3 For

the JTAG loading circuit (see schematic on page 8). PicoBlaze Spartan-3E Starter Kit Initial Design 6 Frequency Counter Logic Delay ensures counters

From my reading of the schematic, that is the connection for your frequency counter, so it is most likely a BNC jack. Data sheets for the two IC's (and their pinouts) are here: CD4017 TLC555...

555 Timers are very fun to encounter and experiment with. They can be used as a timer and can be set to a certain frequency. In Part II of Electronic Project I, we created a circuit that would get an LED to flash. This time we are going to add a speaker so that we can hear the frequency that is...

Several years ago I had a requirement to measure the rotational speed of some cooling fans. Ordinarily I would have put a drop of white-out on a fan blade, shone a bright light on it, and measured the frequency of reflected light with a phototransistor. Unfortunately the fan guard and filter scr...

Hey Guys, Shawn33 makes a good point. It might not be as simple as cutting down or defeating an analog voltage. If it is Pulse Width Modulation, the apparent voltage read by the voltmeter will be very misleading. For example, the 1.3V reading would actually be a 0 to 5V pulse at a rela...

Part I and II focused on components, but I felt that chips needed more clarification before I begin to use them in a project. This entry focuses on all you need to know about chips before you insert them into the breadboard. Different projects will focus on different kinds of chips, which will b...

what is schematic diagram of electrical connection in construction site.also what is schematic diagram of ELCB in electrical pannel.

New laws to counter illegal downloading will be intrusive and ineffective, say internet service providers

wheather in the output side of an variable frequency drive harmonics will be created or not?

Could anyone give a simple wiring schematic to bench test a Epsilon body with the gm electric power assist?

Fixed frequency operation at high output power with frequency reduction at low output power brings efficiency over the total load range.
