| It all started with the Measurement Filter for Class D (100540-1) published in issue 415, July/August 2011. It was designed to handle large...
| The PWM power stage discussed in the previous instalment (June 2009) can be used perfectly well on its own. But a matching preamplifier with...
| There are plenty of designs for simple audio power amplifiers. These generally have a class-AB or class-B topology. Here we present a very c...
| The technical demands on microphones used with radio equipment are not stringent in terms of sound quality: a frequency response from around...
| The AN7147 Dual 5.3-watt Audio Power Amplifier from Panasonic is listed as a ‘replacement type’ so hopefully will be around for some time to...
| Phonographs are gradually becoming a rarity. Most of them have had to yield to more advanced systems, such as CD players and recorders or (p...
| The circuit is intended for carrying out harmless experiments with high-voltage pulses and functions in a similar way as an electrified...
| The resistive nature of the complementary outputs of a eMDS logic inverter may be used to create a voltage gain stage which allows an ou...
