Should PCM receivers really cost more?
Harry,
For sometime now I have been trying to obtain the schematic for an IPD receiver. It seems you may be the man to answer a few questions I have relating to IPD operation.
Quote.
"When signal strength is weak the IPD widens its selectivity"
Q1. Is this the RF signal strength in your statement ?
Q2. IPD - If it means Intelligent Pulse Decoding how can it digitally decode the RF signal which is A.C. ?
Q3. How does it change the selectivity and when does it know to do this?
Q4. What is the composition of the circuitry that allows this function to operate correctly in the close vicinity of other transmitters ?

"It widens its selectivity. On that frequency."
Q5. Is it feedback that makes it frequency selective on that frequency and if so where is it being sensed from ?
Q6. What happens to the sensitivity if the selectivity is increased on that freqency ?
Q7. Is this a technique using only passive components or are active components also used ?
I'm sure a lot of technical readers out there would also like to understand the vagueries of IPD. I for one look forward with interest to you de-mystifying IPD.
