kdor Posted August 15, 2010 Report Share Posted August 15, 2010 I don't have an oscciliscope, is there any other accurate means of obtaining a signalsfrequency?Know anything about residual frequency, or how to achieve anti-gravity?I also wired up an invention that takes oily,contaminated waste water and through aprocess,recycles the water and separates all dirt,fuel/oils,ect. For use at any companythat has ,operates,or uses vehicle/machinery wash racks.Complies w/EPA,local laws.If any interest,I could share design schematics.

Kevin Weddle Posted September 14, 2010 Report Share Posted September 14, 2010 You can guess as to an approximate frequency range using other measurement devices. But an oscilloscope or other frequency measuring device is required at higher frequencies and lower amplitudes. Quote Link to comment Share on other sites More sharing options...
Silent Jack Posted September 15, 2010 Report Share Posted September 15, 2010 I'd be interested in how your process works and what tech it entails. Quote Link to comment Share on other sites More sharing options...
Kevin Weddle Posted September 15, 2010 Report Share Posted September 15, 2010 The signal can be converted to a clock signal with an opamp. A counter will set the last bit after a number of clock pulses. This bit can be used to power an LED, which will flash. An analog voltmeter or digital voltmeter can measure AC up to a maximum frequency and amplitude across a capacitor. But it would not be very accurate.
