1-07-1978 | When using digital circuits such as character generators to display information on a TV screen the digital signals frequently have a...

1-07-1978 | When used in conjunction with an FM front end, the following circuit for an IF strip will form a handy pocket FM receiver. The heart...

1-07-1978 | The braking efficiency of a car can be found simply by measuring the time taken to bring the car to a halt from a known velocity. The...

1-07-1978 | In transceivers the desired frequency is often dialled into a frequency synthesiser by means of thumb wheel switches. This type of swi...

1-07-1978 | The circuit shows an application of Cadac`s V-Cat or Voltage Controlled Attenuator as a Limiter/Compressor control element. In ope...

1-07-1978 | Using almost any operational amplifier it is possible to build a simple and reliable squarewave oscillator. The design is free from...
