Hi Brian , I had that happen to mine at one time.....I no longer have it of the service manual now, but i recollect if you take the bottom off there is a wall across the the back at the LHS a couple
These days you might have a custom 24 bit A/D converter at the front end of an HF receiver for [the modern day equivalent equivalent of WW2 monitoring stations] that digitises the entire HF spectrum
Alberto, I guess not. I know about some 14 bit ADC's up to 100MSPS and a while ago I received a flyer from Analog Devices promoting a 16 bit / 80 MSPS ADC, but it costed about 1 kEuro and they give n
Dear Alberto, Do really exist A/D converters capable of 24-bit resolution at 30 MHz bandwidth ? Why one need 24-bit? Though 16 bit is adequate for most SW,MW,LW recievers. 16 bit yelds abt 90 dB dyna
Why one need 24-bit? Though 16 bit is adequate for most SW,MW,LW recievers. 16 bit yelds abt 90 dB dynamic range (every bit exept sign bit yelds 6dB). But this is dynamic range if there is no filter
Dear Alberto, I am not quite sure I do agree with you. While it is true that narrowing the bandwidth the energy of the noise inside that bandwidth do decrease while the signal doesn't (provided it is
Why one need 24-bit? Though 16 bit is adequate for most SW,MW,LW recievers. 16 bit yelds abt 90 dB dynamic range (every bit exept sign bit yelds 6dB). This means that 1 bit give a sufficient MDS? The
For a normal A/D sampling at a rate approaching the Nyquist bandwidth (Fsample / 2) , Signal to Quantisation noise ratio is approximately 6.N - 1.7 - (peak to mean ratio). Where N is the number of bi
