i want a desing for a filter,so that i can get a 40 khz as an output,plz,just send me the schematic using an amplifier,ok,10x for ur help

The Oscilloscope and Function Generator

Find the maximum wavelength of photons that can generate carriers by being absorbed in the following semiconductors (respective band gap is given in parentheses): Ge (0.66 eV); GaAs (1.42 eV); CdS (2.45 eV). Are they in the region of ultraviolet, visible or infrared?

how we can draw the aliased sinwave graph?

4. An inclined open tank contains three different liquids A, B, and C with specific gravities of 0.80, 1.0, and 13.6, respectively. What will be the pressure on the bottom of the tank if the liquid surfaces are at the elevations shown? Also what is the absolute pressure at the interface of fluid...
