Some circuit we need to use very high value for the capacitance value of capacitors.For example filter circuit etc. This circuit add capacitance, can use instanced of an difficult which is expensive or very high value. This circuit was analyzed from the quality of impedance only. then there is discharged power as same as real [...]
USB to Serial Adapter RS-232 Serial Port to USB The USB to Serial adapter (converter) lets you use a serial PDA, GPS, cell, etc. with a standard USB port. This adapter is the easiest way to add a serial port to your computer. Many PDAs, digital cameras, GPS units, barcode scanners, and other equipment require [...]
Ensure +5/-5 dual supply for chip TL062 IC3. Gnd is common ps ground, let grounds radiate from ground plane in one side of PCB. R3-R8 is an attenuator that may need to be designed or modified. In output R23 is for protection from shorting of +5V supply, R23 can also go to an unregulated or [...]
