An oscilloscope is an signal analyzer and the function generator is a device that can generate waveform. This video is about how to use oscilloscope and the function generator. In this video, an oscilloscope, a function generator, a circuit box, connector cable and probe are used. First, connect the output of the function generator to the circuit box. The oscilloscope […]
Read moreThis is a video tutorial about oscilloscope. This video explains about the parts on the oscilloscope and their function. Oscilloscope is a tool to display waveform. From the waveform, we can know the voltage and the function time. This video use HP 54645D oscilloscope, probe and function generator. The oscilloscope has two channel, A1 and A2. Set the function generator […]
Read moreThis is a video tutorial for oscilloscope. This video Shows how to oscilloscope. This video uses an oscilloscope, signal generator, probe and simple circuit. The oscilloscope is very useful for signal analysis. To use the oscilloscope, a probe is needed. The probe has edge ground connection and lead connection that is used to connect to the oscilloscope. Beside that the […]
Read moreThis is a function generator video. This video explains about the features of the function generator and their function. The function generator is a tool that can be used to generate the waveform. The output of the generator is a voltage which change regularly over change. The function generator in this video is HP 33120A function generator. The function generator […]

This audio mixer is built with transistors. This audio mixer circuit is unique, not based on low input impedance amplifier. Most of audio mixer circuit is based on low impedance amplifier, so a high resistance signal source point can be summed together without disturbing each other. This mixer circuit is different, since the circuit is based on something like open […]
