| Ci | Limiting amplifier input coupling capacitor |
| R2 | Extraction pulse current limiting resistor |
| Fa.7 | 4.25MHz band-pass filter (impedance: 1 k O) (lt is also possible to use a 4.4MHz filter, but there will be a slight drop in discrimination sensitivity). Input/output impedance: 1 k o |
| Ra | Resistor for adjusting the tuning amplifier output level |
| Ce Le | For fH 2 resonaTor circuit |
| Cii | Ripple filter (tor LC resonator circuit) |
| C12 C14 R14 | Components that determine the discrimination time (chargetdischarge time constant} Charging timca constant = R12 and C14 Discharg time constant = R,4 and C14 |
| Ris | Resistor for absorption of outputleakage |
