Does anyone out there have a copy of the "Wireless World" article that
featured an audio pitch shifter (for feedback suppression). It used a pair
of MC1495 4Q multipliers and a 5Hz quadrature oscillator (I built one and
still have it,but have long ago lost the documentation). It would be
sometime around mid 1970s if the datecode of my 1495s is anything to go by.
All I need is the year, month and author's name.
cheers
