- A description of the projects in this directory:-
- -------------------------------------------------
-
- Project5:-
- ----------
-
- This project is a Stereo LF Audio Function Generator signal source.
- This generator will produce a Sinusoidal, Square, Triangle or Noise
- signal in each channel. It has sweep facilities on either channel and
- has the range from 25Hz to 2500Hz.
-
- Project6:-
- ----------
-
- This project is a parallel port Analogue to Digital Converter.
- This device is the interface between the analogue outside world and
- digital internals of the computer. A simple 0 Volt to +5 Volt DC (Direct
- Current) digital meter is in this directory. Also the calibrating
- software (that will be used extensively for future projects) is in here.
-
- Project7:-
- ----------
-
- This is an Audio Wattmeter from 1 Watt to 100 Watts into a low reactance
- resistive load of 7.5 Ohms. It is calibrated at 400Hz Sinewave and
- measures RMS (Root Mean Square) Power Output.
-
- Project8:-
- ----------
-
- This is an uncalibrated RF (Radio Frequency) Probe, used to align
- multiplier stages and output stages of Transmitters. It uses the A-D
- Converter as a level meter only, so therefore it does not need to be
- calibrated. Just build it, plug it in and use it. Its useful range
- is 1MHz to approximately 1GHz.
