Features: Random digital noise. 33 bit shift register. Clock frequency adjustable between 30KHz and 100KHz. Pink noise filter: -3 dB per octave (20 .. 20000Hz.). Easily adaptable to produce "white noise". Specifications: Output voltage: 150mV RMS./ clock frequency 40KHz. Output impedance: 1K ohm. Power supply: 9 to 12VAC, or 12 to 15VDC / 5mA. Features & Specifications To analyse the acoustic properties of a room (usually a living- room), a good pink noise generator together with a spectrum analyser is indispensable. Moreover you need a microphone with as linear a frequency characteristic as possible (from 20 to 20000Hz.). If, in addition, you dispose of an equaliser, then you can not only check but also correct reproduction. H4301IP'1_rev2.pub page 3 Thursday, July 12, 2012 10:18

  1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully.

1.1 Make sure you have the right tools:

 A good quality soldering iron (25-40W) with a small tip.  Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and enables you to make good connections. When solder rolls off the tip, it needs cleaning.  Thin raisin-core solder. Do not use any flux or grease.  A diagonal cutter to trim excess wires. To avoid injury when cutting excess leads, hold the lead so they cannot fly towards the eyes.  Needle nose pliers, for bending leads, or to hold components in place.  Small blade and Phillips screwdrivers. A basic range is fine. For some projects, a basic multi-meter is required, or might be handy

1.2 Assembly Hints :

Make sure the skill level matches your experience, to avoid disappointments. Follow the instructions carefully. Read and understand the entire step before you perform each operation. Perform the assembly in the correct order as stated in this manual Position all parts on the PCB (Printed Circuit Board) as shown on the drawings. Values on the circuit diagram are subject to changes, the values in this assembly guide are correct* Use the check-boxes to mark your progress. Please read the included information on safety and customer service * Typographical inaccuracies excluded. Always look for possible last minute manual updates, indicated as ‘NOTE’ on a separate leaflet. 0.000

1.3 Soldering Hints :

1- Mount the component against the PCB surface and carefully solder the leads 2- Make sure the solder joints are cone-shaped and shiny 3- Trim excess leads as close as possible to the solder joint H4301IP'1_rev2.pub page 4 Thursday, July 12, 2012 10:18

DO NOT BLINDLY FOLLOW THE ORDER OF THE COMPONENTS ONTO THE TAPE. ALWAYS CHECK THEIR VALUE ON THE PARTS LIST! REMOVE THEM FROM THE TAPE ONE AT A TIME ! H4301IP'1_rev2.pub page 5 Thursday, July 12, 2012 10:18

  1. Turn trimmer RV1 to its centre position. 2. Connect a power supply : AC, 9 to 12 V then between points GND and V. DC, 12 to 15 V (battery or power supply) then - to GND and + to V. 3. Connect the output (OUT, GND) to the input of a spectrum analyser, using a screened flex (screen to GND). Now adjust the noise signal using trimmer RV1 so as to obtain as flat a reproduction characteristic as possible. Especially pay attention to the higher frequencies (adjust spectrum analyser sensitivity if necessary). Remark: the nature of the lower frequencies (32 and 64Hz) makes their read-out unstable. FOR THOSE WHO LIKE TO EXPERIMENT : By adapting C1 you can also modify the clock frequency (pin 3 of IC2) of the shift register (e.g. C1=18pF for a clock frequency up to and beyond 500KHz), so as to obtain a "white noise" at 500KHz and to adapt the filter (C2=100pF, do not fit C4 through C9). Output voltage will drop down to +/- 100mV RMS. Test & adjustment H4301IP'1_rev2.pub page 9 Thursday, July 12, 2012 10:18
