Elektor Electronics, September 2007PDF | English | 6.8 MB Good and Occasionally Favourable You might think that amplifiers are like sand on the beach. But if you restrict your search for fully assembled amplifier modules to hi-fi applications and omit modules for other applications, the range of available products shrinks quite quickly. For this test, we selected eleven different modules from various manufacturers, with an output power range extending up to nearly half a kilowatt.
Digital Inspector This four-channel logic analyser is compact and can be battery powered. The maximum sampling rate is 2 MHz and the circuit has sufficient memory to store 1024 samples of the signal. The dot-matrix display with a resolution of 64 by 128 pixels shows a clear representation of the digital signals.
Ultrasound Receiver Using a balanced mixer, we can make an ultrasound receiver that allows us to hear bat sounds. The Software Defined Radio (SDR) previously described in Elektor Electronics May 2007 makes an ideal starting point.
