Now in our earlier talks we saw that the N-channel Enhancement-mode MOSFET or e-MOSFET works nicely when we supply it with positive input voltage, so this is very important to remember. This type of MOSFET has very high input resistance, almost close to infinity, and because of that we can use it easily like a […]

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, […]
