In a full-wave rectifier circuit, the input frequency is $50 \, Hz$. The fundamental frequency of the ripple is ....... $Hz$.

The output current versus time curve of a rectifier is shown in the figure. The average value of output current in this case is

The value of the form factor in the case of a half-wave rectifier is

If a square signal of $10 \ V$ (varying from $+5 \ V$ to $-5 \ V$) is applied to a $P-N$ junction diode as shown,the output signal across $R_L$ will be:

In the circuit shown in the figure, determine the output waveform and the output d.c. level of $V_0$.

$A$ diode detector is used to detect an amplitude modulated wave of $60\%$ modulation by using a condenser of capacity $250\, pF$ in parallel with a load resistance $100\, k\Omega$. Find the maximum modulated frequency which could be detected by it.
