Nicholai L’Esperance, Timothy Platt, Mustapha Slamani, Tian Xia · IEEE Transactions on Circuits & Systems II Express Briefs · 2016
Multitone test is an effective technique in many wideband circuit test applications. However, the traditional multitone test signal generation methods are complex and/or time consuming. In this brief, a new approach utilizing orthogonal frequency-division multiplexing technique is developed, which can effectively produce multiple frequency tones concurrently with fine resolution and low design overhead. For validation, filter test characterizations are performed and demonstrated.
