The white noise generator
In the figure is the ICMM5837 wide-band white noise generator, the white noise is generated by the 3dB filter of the 10Hz to 40KHz octave. The noise has flat frequency distribution within 20Hz to 20kHz. The output is added on the 1Vp-p noise on the 8.5v DC LEV. This circuit is mainly used to the controllable noise source. Components selecting: integrated circuit IC: MM5837; capacitor CI:100μ25V,C2:1μ50V,C3:0.27μ63V,C4、C5:0.047/63V,C6:0.033μ63V. Resistor RI: 6.8kΩ,R2:3k,R3:1k,R4:300Ω, all of which are l/8WRJ type.
