The digital multimeter is a powerful assistant for measuring electrical signals. Although it is called a “universal” meter, its common functions are limited to measuring voltage, current, and resistance. Voltage and current measurements also include AC and DC ranges. In addition, some multimeters can measure inductance, capacitance, continuity, diode forward voltage, transistor current gain, counting … Read more

01 What Went Wrong to Study Passive Probes It all started with a question: Can a 1X passive probe be used to match a 50-ohm or 75-ohm system like a coaxial cable? Experienced individuals would immediately answer no, because even a 1X probe has a significant resistor in series. I happened to have a discarded … Read more
First, what is a Digital-to-Analog Converter (DAC)? A DAC is used to convert digital samples in bit form into analog waveforms of current or voltage. In short, a DAC is used to reconstruct an analog signal from a digital signal. The process of reconstructing an analog signal from a digital signal is as follows. First, … Read more
