Finding TS Parameters, Fs 59Hz,RE: TS-6943
OK....picked up the AF generator on-line, ran a signal line so I could drive the missus ''All-in-one" type integrated. This was one of those cheap chip-amp versions. But getting in dialed in. Picture this my 14YO 'Rugby boy just out of the shower at 3:00 AM...." com'on I need you now for our experiment. It's so nice to break out the meter, pen in hand writing down dataBy the time we were done my boy was making the AF generator sound just like a chirping bird....so much fun. I think I'll let him loose on the generator & see what he comes up with..thing is I don't have any LOG paper to graph this out right. Fs seems right at 59 Hz, .421VAC, at 35 Hz I got .208VAC, nearly half at -3Db.90 Hz gets me .203VAC.
35Hz .208 58 Hz .418 59 Hz .421 60 Hz .418 90 Hz .203 __________________________________________________ __Rick......... |
