0 2151 0 Frequency Chart on Digital Chips (up to 1 MHz) Frequency Chart on digital microcircuits (up to 1 MHz)

Frequency meters built according to the “slow” scheme are popular among radio amateurs because their scheme is simpler and does not require the use of registers or triggers to memorize previous measurement data. But, the lack of such frequency meters is their slowness. Multi-digit frequency without a switch ...

0 2661 0 Analog Frequency Meter on Chips Analog Frequency Meter on Chips

Analog frequency counter allows you to monitor the process dynamics when measuring frequencies. This is especially important when it is necessary not only to measure the true value of the frequency, but also to trace its changes over time. Frequency counters with digital readings are more accurate, but also more complex according to the scheme ...
