This simple circuit is nonlinear passive on low pass frequency filter. It ‘s small size and easy to made for do not used the external power supply, but refuse a lot of noise ripples and need to a input voltage is stable. The circuit works best, when the signal level is importantly higher than the [...]
The analog to digital converter (ADC) is a commonly required in most of the projects. Analog voltage measurement can be done using the ADC hardware built in together in a PIC. The picture below show a simple setup for measuring the voltage through the adjustment of the potentiometer. PIC used in this example come with [...]
The circuit diagram shows two LT1398’s from Linear Technology used to create buffered color-difference signals from RGB (red-green-blue) inputs. In this application, the R input arrives via 75? coax. It is routed to the non-inverting input of amplifier IC1a and to 1.07-k? resistor, R8. There is also an 80.6-? termination resistor R11, which yields a [...]
