In one of our projects we required several matched silicon diodes for accomplishing a perfectly balanced modulation design. We could easily construct it through a 9 V battery for the […]

This simple capacitor tester can be used to identify the values of unknown capacitors. This bridge design was actually built to come across values for odd, unmarked or unknown capacitors. […]

Eventhough a common multimeter is appropriate for almost all DC voltage measurement it may at times demonstrate to be insufficient. This can be the situation when designing measurements on higher […]

ON SEVERAL events it is really beneficial to manage to establish the frequency of an audio signal. Usually, the consistency and cost of a commercial frequency meter is not really […]

There are numerous potential applications currently to explain the use of a noise level meter – for example, monitoring the sound output at dances, discos etc. The unit explained in […]

This simple and easy affordable millivoltmeter circuit possesses three measuring ranges of 10mV, 100mV, and 1V. RMS full scale sensitivity. The frequency response includes 1 dB points at around 20 […]
