Teknikis for Noise Reduction

  • SOOCE 11; FLT: 0 AF3; SOOCE P low-noise transistor: FI1; FLT: 1 1; ASA3; Devices specically enceed y for low - noise applications are preferable.
  • FLT: 0 = 033. Optimize biasing: 13.FILT: 1 Propet biasing reduces the transistor noispe figure.
  • FLT: 0 FLT; AF3; Implement filtering:
  • FLT: 0: 33; Use diferensiasi konfigurasi: 501; FLT: 1; Averential amplifiser can cancel oui-mode noise.
