A signal w$($t$)$ that has values so that $6$w $($t$)6$ is a $4-$bit PCM encoded using a uniform quantizer characteristic. The coding of the quantized levels to bits is lowest level goes to $0000$ and highest level goes to $1111$ in succession. a$.$ Find the maximum value of the quantization error signal in Volts. b$.$ Find the peak quantization SNR of the signal. c$.$ For two sample values of $-0\mathrm{.}7$ Volt and $+2\mathrm{.}3$ Volt, find the corresponding quantized values wq and binary PCM signals. d$.$ Choose and give $2$ input values between $-0\mathrm{.}6$ Volt and $+0\mathrm{.}6$ Volt for which quantization error is zero
