Use your PC like an Oscilloscope
As an electronics enthusiast or a hobbyist, you probably yearn for an oscilloscope to check out those elusive waveforms in your amplifier or radio. However, the cost deters you. A reasonably good oscilloscope will set you back by several hundred dollars, unless you buy a pre-owned piece or get one at the flea market. However, […]
RF Signal Meter Circuit
In this article I have explained the circuit details of a couple of very interesting and sensitive RF signal meters, which can be used for measuring the RF strength of the transmitted waves from the RF source without making any physical contacts with the source. Simple RF Signal Meter using IC 741 A RF signal […]
