        Subject: Re: [Humanist] 33.687: dB or not dB? Or, how engineers think

Dear Henry,

I humbly submit that the authors of your Application Note
made an important mistake when they added the title. It
should read:

   "Everything you ever wanted to know about decibels but
    were afraid to hear..."

Sorry, I couldn't resist.  It's how this engineer thinks.

Best regards,

Tim
