Abstract A rapid prototyping method for designing mixed signal systems has been presented in the paper. The method is based on implementation of the field programmable analog array (FPAA) to configure and reconfigure mixed signal systems. A serial algorithmic analog digital converter has been used as an example. Three converter architectures have been selected and implemented FPAA device. To verify and illustrate converters operation and prototyping capabilities, implemented converters have been excited by a sinusoidal signal. Analog sinusoidal excitations, digital responses and sinusoidal waveforms after reconstruction are presented.

Reactivity Computer merupakan modul elektronika yang digunakan untuk mengukur reaktivitas dari hasil pembelahan inti diteras reaktor. Sebelumnya sinyal keluaran reactivity computer diolah dan hanya ditampilkan pada layar reactivity computer, namun penunjukannya belum terintegrasi dengan sistem IRL. Sehingga saat praktikum pengukuran reaktivitas batang kendali, peserta kesulitan untuk mengambil data karena perhatian peserta terbagi antara tampilan IRL dan tampilan reactivity computer. Agar dapat diintegrasikan dalam sistem IRL, keluaran reactivity computer perlu dikonversi ke dalam besaran digital, baru kemudian diakuisisi ke dalam sistem IRL. Untuk mencapai tujuan tersebut, dalam penelitian ini dilakukan beberapa tahap, pertama pembuatan rangkaian pengkondisi sinyal karena sinyal dari reactivity computer bernilai -10V sampai +10 Volt DC sementara analog digital converter (ADC) yang tersedia hanya mampu mengukur tegangan 0-5 Volt DC. Kedua pengujian rangkaian pengkondisi sinyal. Ketiga pembuatan sistem akuisisi data dari ADC ke IRL dan terakhir pengujian sistem secara keseluruhan. Setelah seluruh tahap dilakukan, nilai reaktivitas dapat ditampilkan di tampilan IRL, dengan perbedaan penunjukan antara display reactivity computer dengan tampilan di IRL sebesar 1.1%.

Capacitor Coupling

A design of capacitor-coupled ECG test system is introduced here. The extremely weak ECG signal was picked up with capacitor coupling sensor, and was then buffered, filtered and magnified to fit the requirement of analog digital converter. The measured data was then converted and processed by a microcontroller. The ECG signal can be recovered and stored, analyzed by intelligent terminal. The test shows that this method is applicable and would be used widely.
