In this session of Logic Noise, we’ll be playing around with the voltage-controlled oscillator from a 4046 phase-locked loop chip, and using it to make “musical” pitches. It’s a lot of bang for the ...

It used to be a major rite of passage for a hardware hacker to acquire an oscilloscope. Until recently, new instruments were rarely in normal people’s budgets, so you probably made do with a used ...

Oscillator is an electronic circuit that makes a repetitive electronic signal, frequently a sine wave or a square wave. It is essential in many different types of electronic equipment. Like a quartz ...

Since the derivation of the Wien network by Physicist Max Wien (prior work was the ballistic bridge by J. C. Maxwell) in 1891, this network has been used in many oscillators’ designs. One of the most ...

This Idea for Design shows how proper component selection can help reduce startup time for gated oscillators. 3. The scope image shows the CMOS gated oscillator with no startup delay. The yellow line ...

Broadcast engineer Scott Todd recently found that a 40-year-old Broadcast Electronics FX-30 FM exciter needed recapping badly. Replacing all the dried-out electrolytic capacitors can be daunting.
