Frequency doubler with 4011. The circuit shows a half wave voltage doubler. Where f double is the desired doubled output frequency.
Frequency doubler circuits frequency doubler with 4011 this is a circuit of frequency doubler using 4011.
Like other doublers this circuit uses both the rising and falling edges of the input signals to produce digital pulses thus effectively doubling the input s frequency. The logic gate must operate from the desired supply voltage and provide adequate speed for the application. The minimum carrier to noise degradation δcnr in decibels caused by an ideal frequency multiplier is. Thus a frequency doubler n 2 degrades cnr at the input signal by at least 6db and a quadrupler n 4 degrades cnr by at least 12db.
