Frequency Counter Preamplifier Circuit at Marie Weeks blog

Frequency Counter Preamplifier Circuit. It works well from 2hz to more than 20 mhz. fundamentally, a frequency counter has three main components: the preamplifier has been built on a own pcb, because it may have to be replaced (if students try to measure line frequency) or it may be useful for other projects. a frequency counter for the experimenter here is a classic workbench general purpose instrument, with better than 26 mvrms. A gate signal generator that produces a very accurate gate time. of course there must be some sort of preamplifier/protection in front of the frequency counter in order to be usable. so has anyone any ideas for adding a 1 hz to 2 mhz preamplifier to the input of this frequency counter kit?.
