Birthday Spectrum Card
OK, so it's really more of a periodogram than a spectrum. And yeah, the centre frequency looks a little off. And you probably wouldn't get that much leakage if you windowed the data properly. Tell ya what: how about you put all that fancy thinking to good use and come up with a clever birthday-themed message to go inside. Something like: Hertz, don't it? Ha! See? There ya go. No charge.

Folded Greeting Card, Size: Standard, 12.7 cm x 17.8 cm, Paper: Signature Matte, Envelopes: White
Really pleased with the card quality. The perfect theme to personalize a birthday celebration. Birthday greeting combined with a Christmas wish for my nieces Christmas Birthday. Perfect! These colours really pop on this Matte finish. The cute funny monkey expressions add humour to a birthday card surprise.

Love this card! My Nephew's 60th Birthday, and I was able to add my own verse inside. Beautiful setup, and I thoroughly recommend Zazzle...

I wanted a personal Birthday card for a dear friend who was turning 84. I was very pleased with the design and the message inside the card. I'm very pleased with the results, and certainly will order Zazzle cards in the future. I certainly recommend these beautiful cards...
