Digital integrated frequency demodulator subcircuit |
摘要 |
A subcircuit for the demodulation of SECAM color-television signals has two signal paths each including a low-pass filter (tp1, tp2) which has the transfer function H(z)=(1+ z-1)5. The amount of area required by the subcircuit on an integrated-circuit chip is thus kept small.
