A 3-input majority logic gate has inputs $X, Y$, and $Z$. The output $F$ of the gate is logic '1' if two or more of the inputs are logic '1'. The output $F$ is logic '0' if two or more of the inputs are logic '0'. Which one of the following options is a Boolean expression of the output $F$?

A $10$-bit analog-to-digital converter (ADC) has a sampling frequency of $1$ MHz and a full scale voltage of $3.3$ V. For an input sinusoidal signal with frequency $500$ kHz, the maximum SNR (in dB, rounded off to two decimal places) and the data rate (in Mbps) at the output of the ADC are \\\\\\\\, respectively.

A positive-edge-triggered sequential circuit is shown below. There are no timing violations in the circuit. Input $P0$ is set to logic ‘0’ and $P1$ is set to logic ‘1’ at all times. The timing diagram of the inputs $SEL$ and $S$ are also shown below. The sequence of output $Y$ from time $T0$ to $T3$ is . image needed to be inserted here

A 4-bit weighted-resistor DAC with inputs $b3$, $b2$, $b1$, and $b0$ (MSB to LSB) is designed using an ideal opamp, as shown below. The switches are closed when the corresponding input bits are logic '1' and open otherwise. When the input $b3b2b1b0$ changes from $1110$ to $1101$, the magnitude of the change in the output voltage $VO$ (in mV, rounded off to the nearest integer) is \\\\\\\. !image(https://uadmin.udsfgecw.tech/file/download/public/public:71dbe329-adb9-40bf-a44c-48e975688624.jpg)
